Subject: fast-export: avoid stripping encoding header if we cannot reencode
X-Git-Tag: v2.23.0-rc0~139^2~2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/ccbfc96dc480a1395f2068c706f53fe0881c8356?hp=ccbfc96dc480a1395f2068c706f53fe0881c8356

fast-export: avoid stripping encoding header if we cannot reencode

When fast-export encounters a commit with an 'encoding' header, it tries
to reencode in UTF-8 and then drops the encoding header.  However, if it
fails to reencode in UTF-8 because e.g. one of the characters in the
commit message was invalid in the old encoding, then we need to retain
the original encoding or otherwise we lose information needed to
understand all the other (valid) characters in the original commit
message.
