25.1; GUD GDB doesn't decode file paths correctly |

Dear maintainers,
It seems that GDB MI doesn't decode file paths correctly, which can
result in some really weird unexpected behaviors.
For example, it attempts to find file
/home/ksqsf/我的坚果云/"/home/ksqsf/\346\210\221\347\232\204\345\235\232\346
\236\234\344\272\221/code.cpp"
I traced down to the source and found that gdb-get-source-file, gdb-
get-source-file-list, and gdb-get-location don't decode file paths
using a correct coding system. (In my case, UTF-8.) Instead, they
simply use 'read'.
Hope this can be fixed soon!
Regards,
_rika

Done.

What documentation did you have in mind?

No, I don't think so. It has some confusing side effects, and in most
cases is unnecessary.

You can tell GDB to stop escaping in strings ("set print
sevenbit-strings", which is off by default), but GDB is under user
control, and the user is legitimately allowed to turn escaping on, we
cannot do anything about that. Plus, there are GDB settings to
control the encoding of text strings that GDB emits based on values of
the variables of the program being debugged.

??? LLDB doesn't have a respectable implementation of the MI protocol
to begin with.
