Re: utf32 support
A 32 bit character type is supported by FreeBSD. Unicode 2012 says utf32 must be a 32 bit signed integer. Unicode only defines the Codepoint character attribute. RTEMS now uses libBSD and newlib. Need kernel to support the Codepoint range of values. Applications can then use additional user-defined character attributes. — John P.S.: UTF32 exists for Unicode in 2012 after consolidation from ISO 10646-2012. The two standards merged.

Re: utf32 support
What does support for UTF-32 entail? Do you have an idea what software functions you are looking for? I see the International Components for Unicode (ICU) has a converter ( https://icu.unicode.org/download) which looks it might be part of a solution. Multibyte character methods defined by POSIX would be in newlib.
