fix-doxygen-unicode.py protected the first argument of each
\doxynewunicodechar{...} from its replacements, then turned every
non-ASCII character left in the file -- the protected ones too -- into
"?" and wrote the file as ASCII. refman.tex's \doxynewunicodechar{⁻},
{²} and {³} became \doxynewunicodechar{?}, and newunicodechar stopped
the build: "ASCII character requested".
The "?" fallback now applies to the unprotected parts of each line
only, and the file is written as UTF-8.
