For each argument on the command line, look for it in the set of all Unicode
|
|
names. Arguments are treated as case-insensitive regular expressions, e.g.:
|
|
|
|
% 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 ***
|
|
HORIZONTAL LINE EXTENSION (9135)
