Ah yes, you're right -- probably ?string $encode = null to match with mb_substr().


I am not sure if that signature makes sense and if the proposed functionality fits into mbstring for that reason. IRIs are defined as UTF-8, any other encoding results in invalid output / results that are not interoperable. As one example paragraph from RFC 3987:


Conversions from URIs to IRIs MUST NOT use any character encoding
other than UTF-8 in steps 3 and 4, even if it might be possible to
guess from the context that another character encoding than UTF-8 was
used in the URI.


The correct solution to me is to build a proper thought-through API as part of the proposed new Uri namespace and not adding new standalone functions without a clear vision.
