One of the above answer provides the solution:

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales

The problem with above solution is that it has to be done on the linux shell. However, if you are providing your code to work on the client machine then this is a bad approach. I also tried executing the above commands using os.system(), but still it doesn't work.

Solution that worked for me is

locale.setlocale(locale.LC_ALL,'en_US.UTF-8')

first  make sure you have the language pack installed by doing    sudo apt-get install language-pack-en-base   sudo dpkg-reconfigure locales

For the record  I had this same problem  but none of the solutions worked  I had upgraded my computer and migrated my PC  I had a a mixed locale english and spanish     locale LANG en US utf8 LANGUAGE  LC CTYPE  en US utf8  LC NUMERIC es ES utf8 LC TIME es ES utf8 LC COLLATE  en US utf8  LC MONETARY es ES utf8 LC MESSAGES  en US utf8  LC PAPER es ES utf8 LC NAME  en US utf8  LC ADDRESS  en US utf8  LC TELEPHONE  en US utf8  LC MEASUREMENT es ES utf8 LC IDENTIFICATION  en US utf8  LC ALL    But  on my new Debian installation  I just selected english as locale   Which finally worked was to reconfigure locales package to add and generate spanish too     grep -v      etc locale gen  en US UTF-8 UTF-8 es ES UTF-8 UTF-8

In trying to get python to spit out names in specific locale I landed here with same problem   In pursuing the answer  things got a little mystical I find   I found that python code   import locale print locale getdefaultlocale    gt  gt    en DK    UTF-8     And indeed locale setlocale locale LC TIME   en DK UTF-8   works  Using tips here I tested further to see what is available using python code  import locale loc list     a b  for a b in locale locale alias items     loc size   len loc list  print loc size  entries   for loc in loc list      try          locale setlocale locale LC TIME  loc 1           print  SUCCES set   12        format loc 1  loc 0       except          pass   which yields  858 entries SUCCES set en US UTF-8   univ  SUCCES set C             c ascii  SUCCES set C             c en  SUCCES set C             posix-utf2  SUCCES set C             c  SUCCES set C             c c  SUCCES set C             c c c  SUCCES set en IE UTF-8   en ie utf8 euro  SUCCES set en US UTF-8   universal utf8 ucs4  SUCCES set C             posix  SUCCES set C             english united-states 437  SUCCES set en US UTF-8   universal    Of which only above is working  But the en DK UTF-8 is not in this list  though it works     What   And the python generated locale list do contain a lot of combos of da and DK  which I am looking for  but again no UTF-8 for da DK     I am on a Point Linux distro  Debian based   and here locale says amongst other LC TIME  en DK UTF-8   which I know works  but not the locale I need   locale -a says  C C UTF-8 en DK utf8 en US utf8 POSIX   So definitely need to install other locale  which i did by editing  etc locale gen  uncomment needed line da DK UTF-8 UTF-8 and run command locale-gen  Now locale setlocale locale LC TIME   da DK UTF-8   works too  and I can get my localized day and month names   My Conclision   Python   locale locale alias is not at all helpfull in finding available locales     Linux   It is quite easy to get locale list and install new locale  A lot of help available   Windows   I have been investigating a little  but nothing conclusive  There are though posts leading to answers  but I have not felt the urge to pursue it

Run following commands  export LC ALL  en US UTF-8  export LC CTYPE  en US UTF-8  sudo dpkg-reconfigure locales   It will solve this   Make sure to match the  UTF-8 part to the actual syntax found in the output of locale -a e g   utf8 on some systems

User · Answer

if I understand correctly  the main source of error here is the exact syntax of the locale-name  Especially as it seems to differ between distributions  I ve seen mentioned here in different answers comments   de DE utf8 de DE UTF-8   Even though this is obviously the same for a human being  the same does not hold for your standard deterministic algorithm   So you will probably do something along the lines of   DESIRED LOCALE de DESIRED LOCALE COUNTRY DE DESIRED CODEPAGE RE    Uu  Tt  Ff   8 if     locale -a   grep -cE    DESIRED LOCALE    DESIRED LOCALE COUNTRY   DESIRED CODEPAGE RE    -eq 1   then     export LC ALL   locale -a   grep -m1 -E    DESIRED LOCALE    DESIRED LOCALE COUNTRY   DESIRED CODEPAGE RE        export LANG  LC ALL else     echo  Not exactly one desired locale definition found    locale -a   grep -E    DESIRED LOCALE    DESIRED LOCALE COUNTRY   DESIRED CODEPAGE RE      gt  amp 2 fi

python looks for  UFT-8  but you probably have  utf8 try installing the  UFT-8 packages with sudo dpkg-reconfigure locales

User · Answer

Not the answer for this question but this question helped me to find the answer for my problem  I had this problem when using inside a Docker container  I solved by installing locales  adding my language to the locale gen file  executing locale-gen  it reads from locale gen  and finally setting LANG to my language  For example  my Dockerfile  RUN apt-get install -y locales RUN echo  quot pt BR UTF-8 UTF-8 quot   gt  gt   etc locale gen RUN locale-gen pt BR UTF-8 ENV LANG pt BR UTF-8

According to this link  it solved by entering this command      export LC ALL C

More permanent solution would be to fill the missing values  in the output shown by command  locale  Output from locale is       locale LANG en US utf8 LANGUAGE  LC CTYPE  en US utf8  LC NUMERIC es ES utf8 LC TIME es ES utf8 LC COLLATE  en US utf8  LC MONETARY es ES utf8 LC MESSAGES  en US utf8  LC PAPER es ES utf8 LC NAME  en US utf8  LC ADDRESS  en US utf8  LC TELEPHONE  en US utf8  LC MEASUREMENT es ES utf8 LC IDENTIFICATION  en US utf8  LC ALL    To Fill the missing values edit    bashrc        vim    bashrc   Add the following lines after the above command  suppose you want en US UTF-8 to be your language    export LANGUAGE  en US UTF-8  export LC ALL  en US UTF-8    If this file is ReadOnly you would be needing to follow the  steps mentioned by The GeekyBoy  The answer given by Dr Beco in Superuser has details relating to saving readonly files   After saving the file do     source    bashrc   Now you wont be facing the same problem anymore

You probably do not have any de DE locale available   You can view a list of available locales with the locale -a command  For example  on my machine     locale -a C C UTF-8 en AG en AG utf8 en AU utf8 en BW utf8 en CA utf8 en DK utf8 en GB utf8 en HK utf8 en IE utf8 en IN en IN utf8 en NG en NG utf8 en NZ utf8 en PH utf8 en SG utf8 en US utf8 en ZA utf8 en ZM en ZM utf8 en ZW utf8 it CH utf8 it IT utf8 POSIX   Note that if you want to set the locale to it IT you must also specify the  utf8    gt  gt  gt  import locale  gt  gt  gt  locale setlocale locale LC ALL   it IT       error  Traceback  most recent call last     File   lt stdin gt    line 1  in  lt module gt    File   usr lib python2 7 locale py   line 539  in setlocale     return  setlocale category  locale  locale Error  unsupported locale setting  gt  gt  gt  locale setlocale locale LC ALL   it IT utf8    it IT utf8    To install a new locale use   sudo apt-get install language-pack-id   where id is the language code  taken from here   After you have installed the locale you should follow Julien Palard advice and reconfigure the locales with   sudo dpkg-reconfigure locales

This error can occur  if you have just added a new locale  You need to restart the python interactive shell  quit   and python  to get access to it

In my opinion  the easiest way to setup the local locale in python  3  is    gt  gt  gt  import locale  gt  gt  gt  locale setlocale locale LC ALL       de DE UTF-8    Then  locale aware stuff just works  if you re on a decent linux distro  and should work on binary distributions of the other OSes as well  or that s a bug IMHO     gt  gt  gt  import datetime as dt  gt  gt  gt  print dt date today   strftime   A  d   B  Y    Sonntag 11  Dezember 2016

For those deploying a docker image and using a locale that isn t shown in the locale -a command  add this line to your Dockerfile RUN apt-get install -y locales This should add all locales to your image  I used de DE which is not part of AWS default Ubuntu server

run this command locale to get what locale is used  Such as       LANG en US UTF-8   LANGUAGE en US en   LC CTYPE zh CN UTF-8   LC NUMERIC  en US UTF-8    LC TIME  en US UTF-8    LC COLLATE  en US UTF-8    LC MONETARY  en US UTF-8    LC MESSAGES  en US UTF-8    LC PAPER  en US UTF-8    LC NAME  en US UTF-8    LC ADDRESS  en US UTF-8    LC TELEPHONE  en US UTF-8    LC MEASUREMENT  en US UTF-8    LC IDENTIFICATION  en US UTF-8    LC ALL       search for the listed locales list in first step in  etc locale-gen file  Uncomment to used ones run locale-gen to generate newly added locales
