The patch below fixes both issues (tested against ofono 1.34).
Should I submit it as a real patch, or there is a possibility that it
would negatively affect other systems?

The documentation for `g_convert` states "Using extensions such as
“//TRANSLIT” may not work (or may not work well) on many platforms.
Consider using g_str_to_ascii() instead."

Thanks for help.
