Mysterious errors in ligatures

Hi, I am having a problem with a font I created. When I type A/C, the slash disappears. In fact, it seems to disappear any time it’s followed by a capital letter. I have to type two slashes for one to remain.

It’s baffling me. Can anyone tell me what I’m doing wrong? Font is here: https://www.dropbox.com/s/8oo7acqmvi4ama5/MusGlyphs%201.30.otf?dl=0

Thanks!

That is because you’re typing in the Preview Toolbar, where the forward slash is used as an escape character. It is documented in the help topic on the Preview in FontCreator.

Type /down and you will see what the slash does in the Preview Toolbar.

If you type a/c in the font test window, the first slash won’t disappear.

Ok, great! Thank you.
