Is it possible to create a ligature in Type Light?

[Zael]

Hello, I just wanted to ask, is possible to make one glyph of two or more characters? I mean ligatures like latin script "fi" and for example arabic "lm" ("لم"), what some fonts have.
If that is possible and it's in Type Light, so how? I couldn't find it anywhere... Thank you in advance.

You can certainly add that glyph to your font by mapping it to its unicode character (fi = FB01), but to have it function automatically as a ligature (ie two characters 'fi' replaced with single character 'fi' in an application) you need to include it as an OpenType feature. You can do that with Type 3.2 full version, but not Type light.
