Gary D. Gregory commented on COMPRESS-638:
------------------------------------------
You should likely check the GZip specification to see how this data is allowed
to be encoded.
> The GzipCompressorOutputStream#writeHeader method uses the ISO_8859_1 to
> write the file name. If the file name contains non-ISO_8859_1 characters,
> some unknown characters are displayed after decompression.
