GLib.unichar_iswide_cjk
function unichar_iswide_cjk(c: String): Boolean { // Gjs wrapper for g_unichar_iswide_cjk() }
Determines if a character is typically rendered in a double-width cell under legacy East Asian locales. If a character is wide according to GLib.unichar_iswide, then it is also reported wide with this function, but the converse is not necessarily true. See the [Unicode Standard Annex #11](http://www.unicode.org/reports/tr11/) for details.
If a character passes the GLib.unichar_iswide test then it will also pass this test, but not the other way around. Note that some characters may pas both this test and GLib.unichar_iszerowidth.
Since 2.12
- c
