Hi, using variable contents with UTF8, yields the following: pkg-config> ./pkg-config --define-variable=x=ö pkg-config Invalid byte sequence in conversion input pkg-config> echo $? 1 pkg-config> git rev-parse HEAD 0e847a2201ace5e53e474c52ad5b51e70607980e (current master) Glib is version 2.42.0-2 (Debian sid). In our particular use-case we put a path name into a variable and that path contains UTF8 characters.
Unfortunately, pkg-config doesn't currently handle non-ASCII correctly. You can add a call to 'setlocale(LC_ALL, "")' at the beginning of main to get past this error (g_option validating the input), but later you'll likely not get back the results you expected. In particular, strdup_escape_shell(), the function used by the parser to escape special shell characters, make the assumption that it's operating on an ASCII byte string. This should get fixed, but I don't expect it to happen really soon. Sorry.
