Ranked in these QuestionsQuestion Ranking
Pro It's simple, beautiful, and stylish
Pro Great for your eyes

The font is very legible due to the distinguished characters it contains.

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 Slightly difficult to use outside of Xcode, Terminal, or Console
The typeface isn't available in Font Book, etc. unless the user imports the files embedded in the apps above.
Con Apple is locking down this font
It's not open in any sense of the word. It even gives warnings if you try to rip it out of the Terminal.app or Xcode bundles. Obviously, Apple only wants it on their tools. This is such a shame. It should work in other editors, too. It's a beautiful font. Apple open sourced swift, why can't they be open with a monospace font?
