Two ways to enable fonts for the MS-DOS terminal:
1. Open the font in BitFonter; click on the fontname (next to the Mac-style font folder icon), open the Font Info dialog; under Encoding and Unicode specify Encoding Mode: CodePage, and Use Table: OEM/DOS. In Additional date (under Encoding and Unicode, choose MS Charset: OEM/DOS. For each font in the family, choose Font Info, under Metrics and Dimensions, go to FON/FNT and remove the checkmark (if any) next to Variable Pitch. (The Font Family should be "Modern" or "Don't care", but I don't know if this is essential.) Save the font with the extension .FON in the Windows\Fonts folder. (If that doesn't work, open one of the existing .FON files from that folder - some are hidden files - and copy the details from the existing .FON file.)
2. To make your new set the default "Terminal" set, use Windows Notepad to edit C:\windows\system.ini. Under [386enh] change the line:
woafont=whatever.FON
to read
woafont=YOURNEW.FON
(Of course, replace these filenames with real ones.). Please post back to report if these procedures work or not.
