code-points clj

(code-points s)

Returns all of the Unicode code points in s, as a sequence of integers.

codepoint-to-string clj

(codepoint-to-string code-point)

Converts any Unicode codepoint to a String.

This is useful because Clojure/Java string literals only support UTF-16 escape sequences, which involves manual construction of all supplementary code points.

combining? clj

(combining? code-point)

Is code-point (a character or integer) a combining character?

non-printing? clj

(non-printing? code-point)

Is code-point (a character or integer) a non-printing character?

null? clj

(null? code-point)

Is code-point (a character or integer) a null character?

wcswidth clj

(wcswidth s)

Returns the number of columns needed to represent String s. If a nonprintable character occurs among these characters, -1 is returned.

wcswidth2 clj

(wcswidth2 s)

Returns the number of columns needed to represent String s, ignoring nonprintable characters (note: this variant is not provided by POSIX, but is arguably more useful on the JVM given how it handles such characters).

wcwidth clj

(wcwidth code-point)

Returns the number of columns needed to represent the code-point. If code-point is a printable character, the value is at least 0. If code-point is a null character, the value is 0. Otherwise, -1 is returned.

wide? clj

(wide? code-point)

Is code-point (a character or integer) in the East Asian Wide (W) or East Asian Full-width (F) category as defined in Unicode Technical Report #11 (and subsequent revisions)?
