Try this character set      t    This does only match a space or a tabulator

Note  For those dealing with CJK text  Chinese  Japanese  and Korean   the double-byte space  Unicode  u3000  is not included in  s for any implementation I ve tried so far  Perl   NET  PCRE  Python    You ll need to either normalize your strings first  such as by replacing all  u3000 with  u0020   or you ll have to use a character set that includes this codepoint in addition to whatever other whitespace you re targeting  such as    t u3000    If you re using Perl or PCRE  you have the option of using the  h shorthand for horizontal whitespace  which appears to include the single-byte space  double-byte space  and tab  among others   See the Match whitespace but not newlines  Perl  thread for more detail   However  this  h shorthand has not been implemented for  NET and C   as best I ve been able to tell

As  Eir  kr   tlendi noted  the accepted solution only considers two white space characters  the horizontal tab  U 0009   and a breaking space  U 0020    It does not consider other whitespace characters such as non-breaking spaces  which happen to be in the text I am trying to deal with    A more complete whitespace character listing is included on Wikipedia and also referenced in the linked Perl answer   A simple C  solution that accounts for these other characters can be built using character class subtraction    s-  r n     or  including Eir  kr   tlendi s solution  you get    s u3000-  r n
