Our experience is that libraries often provide incomplete character mapping
even for standardised encodings. The foremost example is UTF-7, which is still
used reasonably often in email-related contexts (I believe IMAP uses it for
naming folders), which KMail and its supporting libraries have had to supply
above the Qt offering for two decades.

Qt offering includes iconv or ICU, depending on the build, since 2006.
