We already have tvbuff and proto_tree_ routines that take bit offsets and bit counts, so this may be another case where the regular routines don't work; a routine to handle TS 23.038 encoding, taking a *bit* offset and a count of *characters*, might be the best solution here.

I'd vote for proto_tree_add_ts_23_038_item(), though - that encoding isn't used only in the GSM/3GPP/LTE version of SMS.

I would vote for proto_tree_add_gsm_7bits_item() as TS 23.038 talks about 8 bits data and UCS2 encoding also and defines this alphabet as GSM 7bit. We should not put SMS in its name as it has a much wider use in 3GPP / 3GPP2.
