A Survey of Lanna Thai in Northern Region
Notices– Most, except religious, documents are transliterated and published
in central Thai script
– Lanna letters are written by hand, due to the lack of printing system
– Most documents are published by local publishers, making it not so widespread

Future Works
Template topics to study for each script:– Writing system (consonants, vowels, tones, digits, direction,
syllable composition)
– Encoding (alphabetic elements, interchange vs. presentation, composing marks)
– Input method (key availability, input sequence, keyboard layout)
– Output method (display levels, font metrics, shaping, font encoding)
– Sorting order (alphabetic order, classes of character weights)
– Word boundary (word/phrase/sentence delimiters, requirements of word boundary analysis)
