Created attachment 36187 [details] One line patch to add C99 UTF-8 support in identifiers to gcc In response to FAQ > What is the status of adding the UTF-8 support for identifier names in GCC? and the request > Support for actual UTF-8 in identifiers is still pending (please contribute!) my observation is that UTF-8 in identifiers is easy to add to gcc by changing one line in the cpp preprocessor, provided …

While unicode identifiers are supported in gcc, UTF-8 input is not. Therefore, unicode identifiers have to be encoded using \uXXXX and \UXXXXXXXX escape codes. However, a simple one-line patch to the cpp preprocessor allows gcc and g++ to process UTF-8 input provided a recent version of iconv that support C99 conversions is also installed.

C2x adds u8'' character constants to C. This patch adds the corresponding GCC support. Most of the support was already present for C++ and just needed enabling for C2x. However, in C2x these constants have type unsigned char, which required corresponding adjustments in the compiler and the ...

CPP uses the UTF-8 encoding of Unicode. The character sets of the input files are specified using the -finput-charset= option. All preprocessing work (the subject of the rest of this manual) is carried out in the source character set. If you request textual output from the preprocessor with the -E option, it will be in UTF-8.

GCC内部の文字表現は「UTF－8」であるために日本語ではそのままだと文字化けが発生する。 なので、 ① ソースコードをGCCへ読み込ませるときには文字コードを「UTF－8」にして読み込ませる ② GCCからの出力は元のコードに戻す

May 06, 2011 · As long as Microsoft doesn’t add support for the ‘u8’ prefix and better options to enforce UTF-8 as the default encoding for source files, the only way of hard-coding non-ASCII string literals in UTF-8 consists in listing the numeric values for each byte.

If I run on a beautiful modern system with full UTF-8 support, then I definitely want to make full use of this encoding in my development environment. Hex escape sequences like the above one have soon to be seen as an emergency fallback mechanism for use in cases where archaic environments (such as gcc 2.95 ;-) have to be maintained.
