Single stroke font characters not resolving intermittently

Hi there! I’m new to FontCreator. I created a single line font from an existing regular font, but when I test it in Font Creator or export it as a single stroke font, some of the characters are replaced with the high-logic symbol. The weird thing is that the characters that are replaced change each time I test it in FontCreator.

You can see that the high logic symbol replaces different characters in the below images. What am I doing wrong here that’s causing this?

The logos will disappear when you register the program.

Okay so I have to pay for the full version before the symbols disappear?

As mentioned in the dialog that is shown before the Font Test dialog is shown, this is only happening during the trial period.

So yes, you will need to buy a license. This way you can try our software to make sure it suits your needs.

This is the best news I’ve ever gotten! Happy to buy the license to solve this problem. Thank you!
