DWARF version 3 added the DW_AT_use_UTF8 flag on the compilation
unit to indicate that strings are encoded with UTF-8. If the flag
is present, you can assume all strings are UTF-8. Unfortunately,
in the absence of that flag, there is no specified encoding.
DWARF version 5 strongly recommends UTF-8 but does not require it.
