[Bug-tar] Bad filenames cause tar to produce bad pax archives

[Lars Gustäbel]

Hello!

I noticed that tar with the --format=pax option will produce invalid archives
when it encounters filenames that it cannot convert from the user's charset to
utf8.  In src/xheader.c the function code_string simply copies the input string
to the output string in event of an error during utf8_convert. The problem
seems to be known - there is a FIXME tag in the comment. However, I'd favor the
solution from the comment (report an error) instead of silently producing a
corrupt archive.

Regards,

I have come to believe that the whole world is an enigma, a harmless enigma
that is made terrible by our own mad attempt to interpret it as though it had
an underlying truth.
