U+16B21 "𖬡" Pahawh Hmong Consonant Rau Unicode Character

U+16B21 "𖬡" Pahawh Hmong Consonant Rau is a character from the Pahawh Hmong script, which was invented in the 1950s by Shong Lue Yang to write the Hmong language. This specific character represents the consonant sound "Rau" and is part of a syllabary system where each character denotes a complete syllable rather than an individual letter. The script was created to preserve and empower the Hmong community's spoken language, which had previously lacked a widely accepted writing system, and it is now used in some educational and cultural contexts among Hmong speakers.
