In View|Options|Preferences|Fonts menu, open the
Default font group by clicking on it and change (use the Change button) all fonts as follows:
- Times New Roman -> ER Bukinist KOI-8
- Courier -> ER Kurier KOI-8
- Terminal -> ER Relcom Terminal
Defaultfont group, you can add a new
KOI8-Rfont group and make it the default.
Win95 Mosaic allows changing font Script at runtime, but does not save it, so this won't work with the GDI.EXE KOI8-R patch.
You can't enter russian subject or mail body, report the bug to Mosaic Team asking them to use the Option-specified fonts for mail messages.
