yes, I know, but, quoted from their FAQ:
# Why do I see accentuated characters as UTF8 escape sequences?
This is so because Ayttm is a gtk1 application. Give a look at your LANG and LC_ALL environment variables, and if they contain something about UTF, try running ayttm after removing these parts. On Redhat 8 & 9 systems, you can fix it in /etc/sysconfig/i18n too.
