interestingly that RFC seems to use UCS-2 interchanably with UTF-16 There was an excellent discussion of WTF-8 (like UTF-8 but with surrogates) somewhere on the ineternet (I thought wikipedia, but I can't find it now) https://unicodebook.readthedocs.io/unicode_encodings.html section 7.5. UTF-16 surrogate pairs This bug is mainly motiviated by postgresql only accepting well formed UTF-8. so UTF-8 that encodes uFE01 is rejected and leads to mis-behaviour. -- Jasen. 🇺🇦 Слава Україні -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-dev.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-dev-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
