Set to enhancement.
For me this enhancement request should be opened in the Harfbuzz bugzilla, not against LibreOffice.

Best regards. JBF

Well, I have reviewed their repo, but they won’t implement it. Maybe we can require their developer to add API to expose the who alternate glyphs under this feature tag, than we make our implementation to select casually.

See: https://github.com/behdad/harfbuzz/issues/427
Comment 3 Volga 2017-08-27 10:28:59 UTC
If HarfBuzz making this feature works as 'salt' feature, then we can create an algorithm to make this feature works as expected.

Hi Khaled,

What do you think about that?

If someone wants to work on this, all power to them. Otherwise the only font I know that uses the rand feature is a font I created myself to tests its support, so very low priority.

Set to NEW according to comment 5.

It’s also hard to investigate which commercial fonts including this feature.
