Thanks Alan, I've tried them "all" but nothing seems to work: ```js const GLib = imports.gi.GLib;
// this works // https://developer.gnome.org/glib/2.48/glib-Data-Checksums.html#g-compute-checksum-for-data GLib.compute_checksum_for_data( GLib.ChecksumType.SHA1, 'the string', 'the string'.length ); // this doesn't // https://developer.gnome.org/glib/2.48/glib-Data-HMACs.html#g-compute-hmac-for-data GLib.compute_hmac_for_data( GLib.ChecksumType.SHA1, 'secret', 'secret'.length, 'the string', 'the string'.length ); ``` If I try to create `utf8` strings I have got: ``` Error: Unsupported type gint64 for (out caller-allocates) ``` so `GLib.utf16_to_utf8` is not usable here. Should I file a bug?
