3.检查输入字符串是否含有有效utf8文本 voidfix_utf8_string(std::string&str) { std::stringtemp; utf8::replace_invalid(str.begin(), str.end(), back_inserter(temp)); str=temp; } 这个函数会将字符串中的非utf8编码的文本全部替换。 附录:Unicode,UTF8,UTF16,UTF32之间的区别 摘自:知乎日报 很久...
the string that need to be escaped. For ** example, in the case above where the string was composedof 100 0x27 ** characters, the offset might be 0x01. Each of the 0x27 characters would ** then be converted into an0x28 character which would not need to be ** escaped at all ...

-fwide-exec-charset=charset Set the wide execution character set, used for wide string and character constants. The default is UTF-32 gcc-4.8.2 Last change: 2013-10-16 12 GNU CPP(1) or UTF-16, whichever corresponds to the width of "wchar_t". As with -fexec-charset, charset can be...
The signature of functions, which expect a string by value, isn't changed any more. Before,Delphi2Cpphad changed the code to pass a constant reference of the string instead. This is more efficient in C++, since it avoids copying the character array, but a manual post-processing of the co...
