Oct 30, 2010 · Unicode and std::string in C++. Ask Question 9. 2. ... The way I understand it, std::string does not care about the encoding, only the bytes, so when I pass it a unicode string and write it to file, surely that file should contain the same bytes and be recognized as a UTF-8 encoded file? c++ string file unicode. share improve this question.
https://stackoverflow.com/questions/6028093/unicode-stdstring-class-replacement
I'm looking for suggestions regarding unicode aware std::string library replacements. I have a bunch of code that uses std::string, its iterators etc, and would like to now support unicode strings (free or open source implementations preferred, regex capabilities would be great!).

I was in charge of the unenviable task of converting a 6 million line legacy Windows app to support Unicode, when it was only written to support ASCII (in fact its development pre-dates Unicode), where we used std::string and char[] internally to store strings.

Those who delayed their Unicode support tend to use a 32 bits wchar_t. Newer standards don't change much. Mostly there are literals for UTF-8, UTF-16 and UTF-32 encoded strings and there are types for 16 bits and 32 bits char.

This can come in handy, for example, when you have some cross-platform C++ code that stores UTF-8-encoded Unicode strings using the STL std::string class, and you want to pass that text to Unicode-enabled Win32 APIs, which typically use the UTF-16 encoding.

Unicode, localization and C++ support. ... Converting between byte string std::string and wide string std::basic_string<wchar_t> ... oh no. Writing code that works as expected with any valid Unicode string will most definitely force you into a situation when you will want to iterate over every code point in a string, convert between lower case ...

Both utf-8 (std::string) and utf-16 (all the others listed above) are variable-length-encodings, which means that you have to look at all characters before them inside a string to find out which is actually the n'th codepoint (~basic unicode-symbol).

Return value. Returns the uppercase form of ch if one is listed in the locale, otherwise returns ch unchanged. [] NoteOnly 1:1 character mapping can be performed by this function, e.g. the uppercase form of 'ß' is (with some exceptions) the two-character string "SS", which cannot be obtained by std::toupper. [] Possible implementatio

Apr 22, 2013 · On Windows (in Visual Studio specifically), when you write "Bancé", you're actually writing "Banc\xe9" (on sane systems, such as Linux, you actually get "Banc\xc3\xa9", but that's another story) When you use wstring's range constructor, it performs a static_cast for each char in your string to form a wchar_t, so it converts '\xe9' into L'\xffe9', which you see as a box.
