Convert non-ASCII characters to UTF-8 or C-string literals

Comments are converted to UTF-8.

Strings which are part of executable code are converted using C-string hex literals. A comment with the intended UTF-8 character is appended to such lines.

The "c"-looking character in mpa.c was actually a small cyrillic "s" (i.e. "с").
