latin

I am working on a C++ project that need to get data from unicode text . I have a problem that I can't lower some unicode character . I use wchar_t to store unicode character which read from a unicode file. After that, I use _wcslwr to lower a wchar_t string. There are many case still not lower such as: Đ Â Ă Ê Ô Ơ Ư Ấ Ắ Ế Ố Ớ Ứ Ầ Ằ Ề Ồ Ờ Ừ Ậ Ặ Ệ Ộ Ợ Ự which lower case is: đ â ă ê ô ơ ư ấ ắ ế ố ớ ứ ầ ằ ề ồ ờ ừ ậ ặ ệ ộ ợ ự I have try tolower and it is still not working. If you call only tolower , it will call std::tolower from header clocale which will call the tolower for ansi character only.

I have been given an export from a MySQL database that seems to have had it's encoding muddled somewhat over time and contains a mix of HTML char codes such as & uuml; and more problematic characters representing the same letters such as ü and à . It is my task to to bring some consistency back to the file and get everything into the correct Latin characters, e.g. ú and ó . An example of the sort of string I am dealing with is Desinfektionslösungstücher für Flächen Which should equate to 50 Tattoo Desinfektionsl ö sungst ü cher f ü r Fl ä chen 50 Tattoo Desinfektionsl ö sungst
