The only string that needs to be converted back to UTF-8 is the
sources file names string (couldn't it be done by hacking the
gdb-get-source-file-list function?).

I think that would be a nice option if gdb had a flag to disable these
octal sequences for the mi protocol. It would make everything easier.

Nice! I'll try it out when you commit.

Well, but I wouldn't have a good source debugging interface. In fact
the "M-x gdb RET" doesn't fails, it only doesn't load the buffer for
the source code (it behaves like standard gdb without tui).

Thank you!
