Card template name invalid/unsafe characters

iliekprogrammar · March 22, 2025, 4:51am

What characters can cause problems for card templates? I know for fields that any of ":{} are problematic. i have strings that would go into making models, i’m working on validation that would help to prevent unexpected problems.it’s part of my larger tool for making models.

EDIT: from a quick glance at UI strings, i’m guessing there’s no characters explicitly made invalid for card template names. or even note type names. i’ll leave this open if anyone cares to give insight.
