Fraser script
Tones and nasalization are written with Roman punctuation marks, identical to those found on a typewriter.When transcribing exotic rimes (diphthongs or nasal endings), letters ꓮ and ꓬ can work like vowels just like English letter Y, making Fraser script behave like an abjadic alphabet like the Roman instead of an abugida like Tibetan; meanwhile space works like a delimiter like a Tibetan tseg, making a final consonant (such as ꓠ) possible without necessity of a halanta sign: 凉粉 ꓡꓬꓮꓳ ꓩꓷꓠ reads as /li̯ɛw fən/ rather than as ꓡꓬ ꓮ ꓳ ꓩꓷ ꓠ /li̯ɑ ʔɑ ʔʊ fə nɑ/.Lisu punctuation therefore differs from international norms: the comma is ⟨꓾⟩ (hyphen period) and the full stop is ⟨꓿⟩ (equal sign).The understrike (optionally a low macron) indicates the Lisu "A glide", a contraction of [ɑ̂] without an intervening glottal stop.The Fraser script was added to the Unicode Standard in October, 2009 with the release of version 5.2.
