Preferences reset, but still won't display capital A from this font. This is crazytown. I just settled on a similar font, but now i'm just intrigued.
That is crazytown! I'm super-interested as well.
Put it in a Photoshop file, import that Photoshop file as a composition, convert that layer to editable text, and see if it behaves.
Convert it into outlines in Illustrator and see if anything looks odd with the path structure.
Try it in AE version 13.2 (CC 2014).
Check your system language settings. I'm reasonably sure this is a Unicode/ OpenType issue.
You are going to love this. If I bring it in from Photoshop and convert the text layer to editable text, the As still disappear. This almost sounds like a sick prank. It is a simple 1920x1080 comp with the word Alpha written in Stirling Bold.
Edit: Creating Outlines of the capital A in Illustrator yielded nothing. Tried to convert .PSD to editable text in AE CC 2014 and get the same result where the As disappear.
Here is a dropbox link to the font if someone wants to test. Maybe something to do with the font? Just so strange that After Effects is literally the only application that can't render the A.
I checked my Language, it's "English - Primary". As far as I can tell there aren't a lot of language preferences in Mac OSX. Unless i'm missing something here?
That is weird.
I can't test it myself because your dropbox file isn't the actual font file - as it's 0 bytes of data, but that's probably good because you shouldn't be publicly sharing a paid-for typeface. If you were to share it for troubleshooting purposes, you should do it in a direct message or in response to a bug report request for feedback or something and not to the public at large.
Speaking of bug reports, file one on this issue. I'm sure the AE team would find it interesting: Feature Request/Bug Report Form
