Common Mistakes
⚠️
Mistake: Using Latin letters (I, V, X) instead of proper Roman numeral Unicode characters
Fix: Roman numeral characters (Ⅰ–Ⅹ) are single-width glyphs designed to look correct. Using Latin letters (I, V, X) can look inconsistent, especially for numerals like Ⅳ (IV) vs IV.
⚠️
Mistake: Using the wrong subtraction notation combining forms
Fix: The standard Roman numeral for 4 is IV (I before V), not IIII. For 9 it's IX, not VIIII. Some clock faces use IIII for aesthetic reasons, but it's non-standard for most uses.
