Script - Lisu

Lisu is a script used to write the Lisu language, spoken by over a million people in southwestern China, Myanmar, Thailand, and India. Developed by missionary James O. Fraser in the early 20th century, it features uppercase and lowercase letters that are visually distinct but share a common Latin-inspired structure, with tones indicated by punctuation-like marks after syllables. The character repertoire includes 48 letters, five tone marks, and punctuation, all encoded for digital text processing. Script handling treats these characters as a unified system for correct rendering, sorting, and search, ensuring that the distinct glyph shapes and tone combinations are preserved across platforms.
