TextMesh Pro Problem generating Font asset with special ligatures

I have a cursive .otf font file, that has special glyph for some combinations of characters, like b followed by some vowels, or v followed by some vowels .

The problem, is the font asset creator doesn't recognize this ligatures, and when this special combinations happen, the result is not the expected.
How can I add this ligatures to the generated font asset?

 

Ligatures are not currently supported. However support for such OpenType features is something that I am working on for Unity 2019.2.

SIDE NOTE: Ligatures do not currently show up in the Font Asset Creator because most glyphs that are the result of some type of substitution are not assigned a Unicode value. They simply exist / are referenced by glyph index in the font file.

Although support for extracting ligature data from font files will not be available until 2019.2 and if all goes well (meaning if I get everything done and working for 2019.2), I might be able to provide basic ligature support late in the 2019.1 cycle as the new FontEngine which will be used in the next TMP release does have the ability to fetch glyphs by index to add them into an atlas texture. So although the version of the FontEngine included in 2019.1 will be missing the ability to extract ligature data, you would still be able to manually define ligatures just like you can manually define kerning pairs. Again, no promises on support for this in 2019.1 but support for the various OpenType features is coming starting with Ligatures, Diacritical Marks and Pair Adjustments (which is Kerning but coming from the GPOS table).

 

Hi

Any update on this?
Is unity 2019.2 or 2019.3 beta support Ligatures?

 

I'm curious about the current status of the OpenType features support. Specifically random substitution of glyphs for a more natural look of a handwritten font we've developed for our upcoming title. Is there any word on this? Cheers!

 

It would be great if ligatures are finally supported by TMPro!

 

Indeed.

Although progress has been slower on this than I would have liked, adding full support for OpenType font features remains a high priority. I am certainly getting more and more requests from users on this.

 

Hi! Stephen any alternative way to access ligatures in textmesh pro? to implement a translation our problem currently is because ligatures doesnt work, textmesh pro translate per character, is there a way to call a character in a font asset?

 

The glyphs used by ligatures are not typically mapped to a unicode character. These are accessed via Opentype Font Features which is not supported yet in TMP.

Until such support is added, you could cheat using a font editing tool to modify the font file and to map the ligatures you need to a unicode character in the private unicode range U+E000..U+F8FF (to avoid conflicts with other unicodes). This would enable you to access then using the unicode these have been mapped to.

 

Thank you! Will try what you have suggested

 

Hi

Any update on this?
Is unity support Ligatures?

 

Font Features like Ligatures is not currently supported. However, this is something that will be supported in the future when using TMP.

 

Hello, there. Thank you for your hard-work for these years.

I would like to know more about how to make use of those private unicodes (U+E000..U+F8FF). Can you explain how it works? Or perhaps do you have any documentation or articles that can help me use those unicodes in Unity?

Thanks in advance!

 

Hi
Any update on ligatures support in unity?

 

Any update?

 

Hi, so I am on Unity 2021.2 and I see the latest pre-release contains support for custom ligatures now:

https://docs.unity3d.com/Packages/com.unity.textmeshpro@3.2/changelog/CHANGELOG.html

Do you recommend people trying this release out? @Stephan_B

My use case is to import Libertinus Keyboard font so that "CTRL" actually show up as the CTRL glyph (U+E173), if you have time please do use it as a test case! Thx in advance.

Yes. I recommend trying out the latest preview releases.

I'll test the above case as soon as I have a chance.
