Con Only characters from the Western charset work in many Windows apps
The font includes all characters for all European languages; however, in most programs using Unicode (such as WordPad or MS Word), only languages using Western charset can use this font. These include English, German, French, Spanish, and Norwegian.
Trying to use any languages like Czech, Hungarian (Central European), Bulgarian, Russian (Cyrillic), or Greek will make the font switch back to default font like Arial or Calibri, even though Monofur itself includes characters for those languages.
Authors didn't bother fixing the non-working Baltic / Central European / Greek / Cyrillic / Turkish character set for those years.
Con Lacks bold+italic
Monofur has a regular italic and bold typeface, but it lacks bold+italic. Syntax-capable editors can better display code based on function/class/context/markup work when at least 4 families are available to display.
Con Relatively expensive
At $179, this font is on the more expensive side.
