Hello, I am still thinking after few years, that why mIRC still uses fixedsys as default font, as it is not unicode support, which includes non suporting Euro (€) letter, and many more letters that are suprted in newer fonts.

A easy feature update would be:

1. Get fixedsys excelsior that is atm 3.01 at this website: http://www.fixedsysexcelsior.com/
2. include that font to mIRC setup
3. Make mIRC use the font as default font after setup, and fontsize: 12

Excelsior is the same font but newer and better support for international languages.
