Convert String to UTF-16 Byte Array in GJS

Question

In my Gnome Extension I would like to call GLib.convert. Sadly it does not work with strings but wants a ByteArray. Now I wonder how to convert a Javascript String into a UTF-16 Byte Array.

Bonus points if this uses some part of the Gnome bindings instead of implementing in Javascript.

Or is it the undocumented and deprecated `ByteArray`? – abergmeier Sep 19 '20 at 09:37 — abergmeier, Sep 19 '20 at 09:37

ByteArray.fromString(someString, 'UTF-16') will convert your JS string into a UTF-16-encoded Uint8Array. This can be passed to GLib.convert (although, since fromString should understand all the encodings that GLib.convert does, maybe you don't need to after that?)
