I'm having trouble creating custom ligatures in the Hebrew language plane, and wondering if anyone can spot my error. My goal is to have an alternate form subbed for two other letters when they are typed sequentially. I can get it to work fine in the Latin area, but not in the Hebrew. I am using an unassigned glyph for the alternate form, named <althe>. Hebrew is a right-to-left language, maybe that affects things? Here is the code I'm using:

script hebr {
# Hebrew
feature StandardLigatures1;
}

feature StandardLigatures1 liga {
# Standard Ligatures
lookup Lookup1;
}

lookup Lookup1 {
# Referenced by feature "StandardLigatures1"

sub aleph bet -> althe;
}

I'm using FontCreator 7.5 Professional, Windows 10, Word 2010. Any help would be appreciated!

We no longer use that version which was released in 2013, so we don't know exactly why it fails on your side.

Over the years we've solved numerous issues related to OpenType layout features, and added several improvements and enhancements, so I'm sure an upgrade would solve the problem.
