Roman numerals wrongly sorted

Hello,

I had a problem naming notes;

at least the mobile version cannot arrange roman numerals correctly: the roman IX is sorted between IV and V;

even if I just name notes III, IV, V, IX, the result doesn’t change

Greetings

Steps to reproduce

see the question

Expected result

III IV V ... IX

Actual result

III IV IX V

Environment

  • Operating system: Android
  • Debug info: ???

Additional information

This is not a bug. The files are sorted alphabetically not by roman numeral.
