Non so quanto bene funzionino queste opzioni (non li uso, ma preferisco trattare i valori letterali stringa come "ASCII only", poiché le stringhe localizzate provengono da file esterni comunque così è per lo più cose come stringhe di formato o nomi di file), ma hanno aggiunto le opzioni come
-fexec-charset=charset
Set the execution character set, used for string and character constants. The default
is UTF-8. charset can be any encoding supported by the system's iconv library routine.
-fwide-exec-charset=charset
Set the wide execution character set, used for wide string and character constants.
The default is UTF-32 or UTF-16, whichever corresponds to the width of wchar_t. As
with -fexec-charset, charset can be any encoding supported by the system's iconv
library routine; however, you will have problems with encodings that do not fit
exactly in wchar_t.
-finput-charset=charset
Set the input character set, used for translation from the character set of the
input file to the source character set used by GCC. If the locale does not specify,
or GCC cannot get this information from the locale, the default is UTF-8. This can
be overridden by either the locale or this command line option. Currently the command
line option takes precedence if there's a conflict. charset can be any encoding
supported by the system's iconv library routine.

Chissà se quando lo src e la codifica exec è l'impostazione predefinita UTF-8, in realtà convalida la stringa letterale come pure formato UTF-8 e genera un errore se contiene sequenze di byte non valide o se lascia passare solo i byte non validi. –
