Anglo-centric ... my word you have a huge chip on your shoulder. Sigil has long supported all platforms and all mainstream languages that Qt supports.

We tried utf-8 ini format back in Sigil 0.9.12 but it was severely broken by Qt (can't encode or decode atomicly which is needed by ini files that support read/writes across multiple instances of Sigil) so we had to revert it in Sigil-0.9.13. as it caused widespread corruption. Check out the ChangeLog.txt or just read the release notes.

Also utf-8 can not encode all binary byte sequences such as widgets storing states, sizes, date-time. In addition Linux allows paths with arbitrary byte sequences.

So not gonna happen.

You should really apologize though for accusing us without any knowledge of why technical choices are made.
