GLib.unichar_decompose

function unichar_decompose(ch: String, a: String, b: String): Boolean {
    // Gjs wrapper for g_unichar_decompose()
}
  

Performs a single decomposition step of the Unicode canonical decomposition algorithm.

This function does not include compatibility decompositions. It does, however, include algorithmic Hangul Jamo decomposition, as well as 'singleton' decompositions which replace a character by a single other character. In the case of singletons *b will be set to zero.

If ch is not decomposable, *a is set to ch and *b is set to zero.

Note that the way Unicode decomposition pairs are defined, it is guaranteed that b would not decompose further, but a may itself decompose. To get the full canonical decomposition for ch, one would need to recursively call this function on a. Or use GLib.unichar_fully_decompose.

See [UAX#15](http://unicode.org/reports/tr15/) for details.
