Fraser script

The Fraser or Old Lisu script, is an artificial script invented around 1915 by Sara Ba Thaw, a Karen preacher from Myanmar and improved by the missionary James O. Fraser, to write the Lisu language. It is a single-case (unicameral) alphabet. It was also used for the Naxi language, e.g. the 1932 Naxi Gospel of Mark and used in the Zaiwa or Atsi language e.g. the 1938 Atsi Gospel of Mark.
The script uses uppercase letters from the Latin script and rotated versions thereof, to write consonants and vowels. Tones and nasalization are written with Roman punctuation marks, identical to those found on a typewriter. Like the Indic abugidas, the vowel is not written. However, unlike those scripts, the other vowels are written with full letters.
The Chinese government recognized the script in 1992 as the official script for writing in Lisu.

Tones.
Tones are written with standard punctuation. Lisu punctuation therefore differs from international norms: the comma is (hyphen period) and the full stop is (equal sign).
The tones , , , may be combined with and as compound tones. However, the only one still in common use is .
The apostrophe indicates nasalization. It is combined with tone marks.
The understrike (optionally a low macron) indicates the Lisu "A glide", a contraction of without an intervening glottal stop. The tone is not always falling, depending on the environment, but is written regardless.
