Best Practices for FNT to PCF Conversion

• →Before converting FNT to PCF, review the font license — some licenses restrict format conversion
• →Check hinting data after conversion: PCF may handle TrueType hinting differently than FNT
• →Verify that all character sets (Latin, Cyrillic, CJK, etc.) survived the conversion intact
• →Test the converted font in both a browser and a desktop application
• →Keep the original font file in case the conversion alters spacing metrics

Troubleshooting FNT to PCF Conversion

• !PCF font doesn't render correctly → check if PCF supports all glyphs present in FNT
• !Licensing restrictions after FNT to PCF conversion → verify the font license allows format conversion
• !Hinting data lost converting FNT to PCF → some font formats like PCF may not preserve TrueType hinting
• !Special characters missing from converted PCF → font subsetting may have removed unused glyphs
