These include non-Unicode sequences, non-characters, overlong sequences or surrogate codepoints encoded into UTF-8. This function can be used to process incoming data incrementally as long as all UTF-8 characters are terminated within the incoming data. Any unterminated characters at the end of ...
QString provides many functions for converting numbers into strings and strings into numbers. See the arg() functions, the setNum() functions, the number() static functions, and the toInt(), toDouble(), and similar functions. To get an upper- or lowercase version of a string use toUpper...

QStringList provides several functions allowing you to manipulate the contents of a list. You can concatenate all the strings in a string list into a single string (with an optional separator) using the join() function. For example: QString str = fonts.join(", "); // str == "Arial,...
