Most people here use the mailing list to read (and reply to) messages.
It looks like your original message on the 8th of July never made it to

The proper way to get bugs solved is by filing a bug in the
firebird-tracker at http://tracker.firebirdsql.org

I do think it is worth looking how other encoders/decoders handle this,
because replacing an unprintable or unknown character with a '?' is in
my eyes a presentation decision that should NOT be handled by an
encoder, but only by the presentation layer. If other encoders handle it
like this as well (eg the built in CharSet objects in Java), we should
follow. On that note, I do think it would be better if Jaybird would
defer to the standard Java encoders or the Java ICU implementation
instead of using handrolled encoders.
