Ah, I'm glad that I'm not alone! I was thinking of asking advice on c.l.f when I get some time to write. I agree with you that it is not clear at all. > (The problem is switching the encoding within the same file; good luck in > finding an editor which supports this.) I don't think there is such thing as a file with multiple encodings, and we shouldn't create such a beast just for Fortran. > a) Have a UCS-4 input file; then both default_'foo' and ucs4_'foo' work. I'd suggest going for that. > b) Expect that for myUCS4_'foo' literals the characters in the quotes are > actually UTF-8. See above, I don't think we want to mix encodings. But, we can support both (a) and (b): if the file is UCS4, go for (a), if the file is UTF-8, go for (b). On a personal note, I would use (b) more than (a): UTF-8 is the way forward, and fixed-width encodings are a real pain for file representation (which is different than internal representation). > Otherwise, I think Fortran misses a good way of inputting non-ascii characters > in an ASCII file. C99 offers '\uXXXX' We already have -fbackslash, I can see us accepting that kind of code with a given option; it would really be useful. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35863
