For what it's worth, GSM has multiple issues:
- GSM is not always in its 7bits packed form (for example, when used in SMPP or
UCP/EMI messages), which means that you need two flavors.
- GSM is often used with the latin1 extension (and I know some other are also
defined) which adds another layer of alternatives.
- the 7bit packed encoding makes it rather unsuitable for iconv interfaces which
assumes that codepoint sizes are multiple of 8 bits: there is no way to push
14bits only for example, you can only transcode 8 gsm codepoints at a time, or
you need to _very_ carefuly craft the data you send (and hence know how the
iconv state works) for it to be useful.
- finally in GSM '\0' is ascii '@', which is a PITA, but arguably not relevant
to iconv.
All in all, I'm not sure that iconv and GSM are a good match.
