UAX #29 rev. 49, Section 5.1 Table 4: the name of U+1CBF is misprinted

Table 4 names U+1CBF “GEORGIAN LETTER MTAVRULI CAPITAL LABIAL SIGN”; UnicodeData.txt 18.0.0 names it “GEORGIAN MTAVRULI CAPITAL LETTER LABIAL SIGN”. The range and the Sentence_Break result are not affected.

Consequence

A reader who searches for the printed name does not find the character.

Proposed correction

Read “GEORGIAN MTAVRULI CAPITAL LETTER LABIAL SIGN”.
