Please do. Cases like this teach us about the proper separation of concerns.

so #asByteArrayDo: produces UTF8 bytes, which is an encoding, so it seems
fixed, IIUC.

Actually, thinking about the original use case, I now feel that it would be
best to remove #zipped/unzipped from String.
The original problem was that
'Les élèves Françaises ont 100 €' zipped unzipped.
does not work (it fails on WideStrings), while we now have

Indeed. Bravo, Sven and all of our other contributors.

Hi Tomo,
Indeed, I stand corrected, it does indeed seem possible to use the existing
gzip classes to work from bytes to bytes, this works fine:
data := ByteArray streamContents: [ :out | (GZipWriteStream on: out)
nextPutAll: 'foo 10 €' utf8Encoded; close ].
(GZipReadStream on: data) upToEnd ut
