Well, then you have a problem, though it is only with old history (before
introduction of "encoding" header in commit object).

Better and more complete solution would be to use to_utf8() function
instead of 'utf8' layer, which when finding invalid UTF-8 sequence uses
$fallback_encoding (by default "latin1", i.e. ISO-8859-1) instead.

In my TODO list is creating PerlIO layer ':utf8-with-fallback' which would
replace all those to_utf8() calls...
