Primarly STR_UNICODE is used only during filling label (+ one assertion),
and when displaying we have no longer information about ENC_* flag.
We could copy it to ->flags, but ->display for strings is wasted, why not use
it?
We can later add STR_ASCII_WSP or bitmask like: STR_SHOW_LEN, etc..
We could avoid STR_UNICODE by adding encoding flags like you suggest[1],
and by fixing tvb_get_string[z]_enc to enforce encoding rules.
Like ENC_ASCII -> replace all chr >= 0x80
ENC_UTF8 -> replace invalid UTF-8 sequence
and so on..
[1] or by forcing users to call proto_tree_add_string() only with string
earlier obtained from tvb_get_string[z]_enc().
Which I think is better solution.
