About this regex
Matches invalid or improperly ordered Thai vowels and tone marks, such as repeated leading vowels, stacked tone marks, vowels without a preceding consonant, tone marks placed before vowels, and malformed vowel-consonant combinations. Ideal for Thai spell-checking, text input validation, and detecting typographical errors where Thai orthographic rules for combining diacritics are violated.
