+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)
