Explicitly use an unambigious font for external key.

[threethan]

Is your feature request related to a problem? Please describe. I am selling a small software utility on itch.io which uses 6-digit alphanumeric license keys. I have had multiple issues where users cannot tell the difference between O and 0 or I and 1 in their external key. This is because itch.io only specifies the font-family as "monospaced" - which is determined by the user's OS.

Describe the solution you'd like Specific an unambiguous web font such as Sono or Roboto Mono

Describe alternatives you've considered A more robust fallback with multiple specific fonts prioritized also "monospaced" would also work for most systems, but still ends up being OS-dependent.
