This is quite useful question  I think that my solution on Windows 10 PHP7 is rather useful for people who have yet some UTF-8 conversion trouble   Here are my steps  The PHP script calling the following function  here named utfsave php must have UTF-8 encoding itself  this can be easily done by conversion on UltraEdit   In utfsave php  we define a function calling PHP fopen  filename   wb    ie  it s opened in both w write mode  and especially with b in binary mode    lt  php        UTF-8           fnc001  save string as a file in UTF-8     The resulting file is UTF-8 only if  strContent is     with French accents  chinese ideograms  etc      function entSaveAsUtf8  strContent   filename       fp   fopen  filename   wb       fwrite  fp   strContent     fclose  fp     return True           0  write UTF-8 string in fly into UTF-8 file      strContent    My string contains UTF-8 chars ie      for un   t   en France     filename    utf8text txt    entSaveAsUtf8  strContent   filename           2  convert CP936 ANSI OEM - chinese simplified GBK file into UTF-8 file      strContent   file get contents  cp936gbktext txt     strContent   mb convert encoding  strContent   UTF-8    CP936       filename    utf8text2 txt    entSaveAsUtf8  strContent   filename      gt    The source file cp936gbktext txt file content    gt  gt Get-Content cp936gbktext txt My string contains UTF-8 chars ie      for un   t   en France 936  ANSI OEM - chinois simplifi   GBK    Running utf8save php on Windows 10 PHP  thus created utf8text txt  utf8text2 txt files will be automatically saved in UTF-8 format   With this method  BOM char is not required  BOM solution is bad because it causes troubles when we do sourcing an sql file for MySQL for example   It s worth noting that I failed making work file put contents  filename  utf8 encode  mystring    for this purpose                                                                    If you don t know the encoding of the source file  you can list encodings with PHP   print r mb list encodings       This gives a list like this   Array      0    gt  pass    1    gt  wchar    2    gt  byte2be    3    gt  byte2le    4    gt  byte4be    5    gt  byte4le    6    gt  BASE64    7    gt  UUENCODE    8    gt  HTML-ENTITIES    9    gt  Quoted-Printable    10    gt  7bit    11    gt  8bit    12    gt  UCS-4    13    gt  UCS-4BE    14    gt  UCS-4LE    15    gt  UCS-2    16    gt  UCS-2BE    17    gt  UCS-2LE    18    gt  UTF-32    19    gt  UTF-32BE    20    gt  UTF-32LE    21    gt  UTF-16    22    gt  UTF-16BE    23    gt  UTF-16LE    24    gt  UTF-8    25    gt  UTF-7    26    gt  UTF7-IMAP    27    gt  ASCII    28    gt  EUC-JP    29    gt  SJIS    30    gt  eucJP-win    31    gt  EUC-JP-2004    32    gt  SJIS-win    33    gt  SJIS-Mobile DOCOMO    34    gt  SJIS-Mobile KDDI    35    gt  SJIS-Mobile SOFTBANK    36    gt  SJIS-mac    37    gt  SJIS-2004    38    gt  UTF-8-Mobile DOCOMO    39    gt  UTF-8-Mobile KDDI-A    40    gt  UTF-8-Mobile KDDI-B    41    gt  UTF-8-Mobile SOFTBANK    42    gt  CP932    43    gt  CP51932    44    gt  JIS    45    gt  ISO-2022-JP    46    gt  ISO-2022-JP-MS    47    gt  GB18030    48    gt  Windows-1252    49    gt  Windows-1254    50    gt  ISO-8859-1    51    gt  ISO-8859-2    52    gt  ISO-8859-3    53    gt  ISO-8859-4    54    gt  ISO-8859-5    55    gt  ISO-8859-6    56    gt  ISO-8859-7    57    gt  ISO-8859-8    58    gt  ISO-8859-9    59    gt  ISO-8859-10    60    gt  ISO-8859-13    61    gt  ISO-8859-14    62    gt  ISO-8859-15    63    gt  ISO-8859-16    64    gt  EUC-CN    65    gt  CP936    66    gt  HZ    67    gt  EUC-TW    68    gt  BIG-5    69    gt  CP950    70    gt  EUC-KR    71    gt  UHC    72    gt  ISO-2022-KR    73    gt  Windows-1251    74    gt  CP866    75    gt  KOI8-R    76    gt  KOI8-U    77    gt  ArmSCII-8    78    gt  CP850    79    gt  JIS-ms    80    gt  ISO-2022-JP-2004    81    gt  ISO-2022-JP-MOBILE KDDI    82    gt  CP50220    83    gt  CP50220raw    84    gt  CP50221    85    gt  CP50222     If you cannot guess  you try one by one  as mb detect encoding   cannot do the job easily

file get contents   file put contents will not magically convert encoding   You have to convert the string explicitly  for example with iconv   or mb convert encoding     Try this    data   file get contents  npath    data   mb convert encoding  data   UTF-8    OLD-ENCODING    file put contents  tempfolder    a   data     Or alternatively  with PHP s stream filters    fd   fopen  file   r    stream filter append  fd   convert iconv UTF-8 OLD-ENCODING    stream copy to stream  fd  fopen  output   w
