I am the creator of Fixedsys Excelsior. The last public release was 2.00, but since that time I had added hundreds of new characters and improved the Cyrillic and Armenian ranges greatly. Unfortunately, I lost all my additions and changes a long time ago and because mIRC with Unicode seemed so impossible (well, we waited a while!) I gave up. Now that I have learned mIRC has Unicode support, I will gladly resume the project. Please let me know if you have any specific requests for character inclusion or changes. You can contact me at gmail.com (name Valentinium). Considering how it went this time I won’t make any promises, but I think it is reasonably possible that I could release an improved version in one month.
I am very happy people use it, thank you for that.
