Is there a way that can be used to make features designed for other language scripts work in custom script?

FontCreator - Font Editor FontCreator - Support

I’m just trying to find a way that those features designed for other language scripts can be used in DFLT or custom languages not only just in the preview box but also can be used in real test.

For example,

script CTOS {					//this is a custom name, also you can choose DFLT, latn, etc.
  feature InitialForms1;
  feature MedialForms1;
}

feature InitialForms1 init {				//this is an Arabic language feature
  lookup SingleSubstitution1;
}

feature MedialForms1 medi {			//also this one
  lookup SingleSubstitution2;
}

lookup SingleSubstitution1 {
  sub a -> b;
}

lookup SingleSubstitution2 {
  sub a -> c;
}

In this case if you type aaa it shows bca. However it is only functionable in the preview box instead of Test Font.
So is there any way to make these features functionable while testing or in-use, even though they are not in a language script that they are designed for?

I’m hopping on that thread as well. I’m working in Russia with a partly French- and German-speaking team, and will soon have to work with Spanish speakers as we’ll visit and do insurance quotes for these houses in Alicante for sale… So, I’ll have to deal with quite the lot of languages!

These forms are not to be used with Latin script, but are meant for Arabic and other scripts that make use of joining properties.

So even though FontCreator supports it, Windows will not use these features for non joining scripts like Latin.
