% find-uname 'small letter a$' 'horizontal line'
*** small letter a$ matches ***
LATIN SMALL LETTER A (97)
COMBINING LATIN SMALL LETTER A (867)
CYRILLIC SMALL LETTER A (1072)
PARENTHESIZED LATIN SMALL LETTER A (9372)
CIRCLED LATIN SMALL LETTER A (9424)
FULLWIDTH LATIN SMALL LETTER A (65345)
*** horizontal line matches ***
