GDB outputs octal escapes in every string, not just in file names, so decoding should be done on a very low level, where we don't yet know what is a file name and what is some other string (like a value of some string variable). We can decode that if we assume that all the strings output by GDB are encoded the same (in your case, probably UTF-8), and keeping fingers crossed that the communications channel between GBD and Emacs never breaks the 3-digit sequence due to buffering issues. I have a prototype fix along the above-mentioned lines which I will commit soon, unless someone has a better idea. You could then patch your gdb-mi.el and use it with those source files. Alternatively, you can invoke GDB via "M-x gud-gdb RET", which doesn't have this problem in the first place. Thanks.
