Opentype features sometimes working and sometimes not

Post by Cazzac »

Firstly, let me thank you for the amazing FontCreator, which I have been using for over ten years to create handwriting fonts for schools.

I'm trying to achieve a joined handwriting effect (this particular one uses dotted letters for for handwriting practice). I'm adding an entry and exit stroke to each letter, then using ligatures to convert an exit followed by an entry stroke into a specific joining stroke.

The joins all work as expected in the OpenType font designer window:

In the test desktop font window there are clearly some problems:

In the test web font window it seems to work fine:

I've also noticed that the letters don't display correctly in the Windows font preview window:

So clearly I'm doing something wrong, but I have spent hours on this and tried so many different variations that I'm tearing my hair out.

Any ideas?

Open the Font Test Window (F5), and note the font name in the top left corner.

Leaving the font test Window open, switch to your word-processor, select the font and test it there. Ignore the Windows Font Viewer — it probably does not support OpenType features like Contextual Ligatures.

Thanks Bikkhu - I have tried what you suggested and the font works correctly in my word processor.

So I can safely ignore the test window problems?

Yes, the Test window supports some OpenType features, but not all. The important thing is to check in the application(s) in which your font will be used.
