I want to compare strings in Persian (utf8). I know I must use some thing like L”گل” and it must be saved in wchar_t * or wstring. the question is when I compare by the function compare() strings I dont get the right result.

If the strings that you want to compare are in a specific, definite encoding already, then don’t use
wchar_tand don’t useL""literals — those are not for Unicode, but for implementation-defined, opaque encodings only.If your strings are in UTF-8, use a string of
chars. If you want to convert them to raw Unicode codepoints (UCS-4/UTF-32), or if you already have them in that form, store them in a string ofuint32_ts, orchar32_ts if you have a modern compiler.If you have C++11, your literal can be
char str8[] = u8"گل";orchar32_t str32[] = U"گل";. See this topic for some more on this.If you want to interact with command line arguments or the environment, use
iconv()to convert from WCHAR to UTF-32 or UTF-8.
