Daniel Wolf <dwolf at dannad dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dwolf at dannad dot de --- Comment #22 from Daniel Wolf <dwolf at dannad dot de> --- Has there been any progress on this since 2015? I'm maintaining a project that uses the International Phonetic Alphabet (IPA) internally. My life would be much easier if I could use identifiers like aʊ or dʒ. Both are valid C++ identifiers supported by Clang, Xcode and Visual Studio, but not supported by GCC. My knowledge of compilers is very limited, so I'm afraid I can't be of practical help. But I'd like to point out that there is indeed demand for this feature -- see for example this StackOverflow question: <http://stackoverflow.com/questions/12692067/and-other-unicode-characters-in-identifiers-not-allowed-by-g#>
