i.e. you add the string literals to the std::string then use c_str() to get a const char* from it. That still won't work if the Add() function takes a different type, but you haven't given enough information to know what you're asking about. #include #include string myStr("My string"); CA2W unicodeStr(myStr); You can then use unicodeStr as an LPCWSTR. The memory for the unicode string is created on the stack and released then the destructor for unicodeStr executes. Instead of using a std::string, you could use a std::wstring. QString to unicode std::string. Your use of the word Unicode is wrong. Unicode is not an encoding, it's a standard, so talking of a "Unicode std::string" doesn't mean anything. A string by itself can't be unicode compliant. An std::string will have a particular "character" type (usually either 8 .

QString to unicode std::string. Your use of the word Unicode is wrong. Unicode is not an encoding, it's a standard, so talking of a "Unicode std::string" doesn't mean anything. A string by itself can't be unicode compliant. An std::string will have a particular "character" type (usually either 8 . How to convert QString to LPCSTR (Unicode) Ask Question 2. 1. QString can always hold Unicode; LPCSTR is never Unicode. This means that you do have to consider what to do with the characters that won't fit. This isn't a "which method to use" question, but a design question. How to convert a std::string to const char* or char*? Sorry for this but i have one question that idk because i read lot that qstring is internally unicode. But if i have different string's or char's how i can do fast the conversion to unicode Utf8?? Apr 12,  · QString converts the const char* data into Unicode using the fromUtf8() function. In all of the QString functions that take const char* parameters, the const char* is interpreted as a classic C-style '\0'-terminated string encoded in UTF i.e. you add the string literals to the std::string then use c_str() to get a const char* from it. That still won't work if the Add() function takes a different type, but you haven't given enough information to know what you're asking about. std::string s = "À"; std::cout. #include #include string myStr("My string"); CA2W unicodeStr(myStr); You can then use unicodeStr as an LPCWSTR. The memory for the unicode string is created on the stack and released then the destructor for unicodeStr executes. Instead of using a std::string, you could use a std::wstring. QString &QString:: operator+= (char ch) Appends the character ch to this string. Note that the character is converted to Unicode using the fromLatin1 () function, unlike other 8-bit functions that operate on UTF-8 data. You can disable this function by defining QT_NO_CAST_FROM_ASCII when .Internally, QString stores UTF encoded data, so any Unicode code point may be Locally encoded 8-bit std::string (as in: system locale). If my QString only has ascii character, I can convert it to std::string or char* as If the QString contains non-ASCII Unicode characters, using this. In windows, I have a class to converter charset between anscii, utf8, unicode. But, I can not transfer it to mac or linux, Is Any one can help me?. The QString::iterator typedef provides an STL-style non-const If unicode is 0, a null string is constructed. The std::string is unable to deal with characters such as "É", "ï". QString converts the const char* data into Unicode using the fromUtf8(). -
