Hi Internals,

During my research into this topic, I discovered that there exists a
multibyte variant of this function in mbstring extension. This raises the
question: should we add a corresponding multibyte variant of
http_parse_query() to mbstring? Is there any usage in the wild of
mb_parse_str()?
I have even asked a question on Stack Overflow about this topic
https://stackoverflow.com/questions/68761695/can-mb-parse-str-produce-different-results-than-parse-str

To me, it doesn't look like parse_str() is useful anymore, but I come from
Europe where things happen mostly using a single encoding. I am not aware
of any problems that parse_str() might have when it comes to multiple
encoding types.
In fact, when looking at the whole input/output encoding feature of
mbstring I am getting a feeling that this is some niche feature that almost
nobody ever uses. While mbstring is useful for dealing with different
encodings, I am not sure if it is common for HTTP requests to be encoded
with anything else than UTF-8.
I would appreciate some input from experts who know more about mbstring and
encodings.

Regards,
Kamil
