Percent-encode a string per RFC 3986. By default encodes everything except
unreserved chars (A-Z a-z 0-9 - _ . ~). Pass allowReserved: true to also
let reserved characters through.
Surrogate pairs (code points > 0xFFFF like emoji 😀, 𝄞, etc.) are encoded as
their UTF-8 byte sequence. For example, U+1F600 (😀) becomes %F0%9F%90%80.
This is correct per RFC 3986 which uses UTF-8 as the default encoding.
Parameters
str: string
The string to percent-encode.
allowReserved: boolean = false
If true, reserved characters (:/?#[]@!$&'()*+,;=) pass through.
