“The Tai Le script has a history of 700–800 years, during which time several orthographic conventions were used. The modern form of the script was developed in the years following 1954; it rationalized the older system and added a systematic representation of tones with the use of combining diacritics. The new system was revised again in 1988, when spacing tone marks were introduced to replace the combining diacritics. The Unicode encoding of Tai Le handles both the modern form of the script and its more recent revision.” - The Unicode Consortium, The Unicode Standard 15.0
