unicharIszerowidth

Determines if a given character typically takes zero width when rendered. The return value is true for all non-spacing and enclosing marks (e.g., combining accents), format characters, zero-width space, but not U+00AD SOFT HYPHEN.

A typical use of this function is with one of [glib.global.unicharIswide] or [glib.global.unicharIswideCjk] to determine the number of cells a string occupies when displayed on a grid display (terminals). However, note that not all terminals support zero-width rendering of zero-width marks.
