Test, validate and match regular expressions
Matches Thai vehicle license plate numbers in two common formats: one to two Thai consonant characters (ก-ฮ) followed by one to four digits (e.g., กข1234), or a single digit followed by Thai consonants and up to four digits (e.g., 1ก5678). The global flag enables finding multiple plate numbers within a larger text. Useful for validating or extracting Thai car registration plates in forms, OCR output, or document processing.
