U+AA7C "ꩼ" Myanmar Sign Tai Laing Tone-2 Unicode Character

U+AA7C "ꩼ" Myanmar Sign Tai Laing Tone-2 is a combining diacritical mark used in the Tai Laing script, an endangered language of the Tai-Kadai family spoken in Myanmar's Sagaing Region. This tone sign is applied above a base consonant to indicate the second of three distinct lexical tones in the Tai Laing language, where tonal distinctions are critical for meaning. Part of the Myanmar Extended-A block, this character was encoded in Unicode version 7.0 in 2014 to support digital representation and preservation of the Tai Laing writing system. Its shape features a small raised horizontal line, differing from the acute or circumflex marks of other tone indicators, and it is written after the base character in Unicode ordering.
