Font Textures to Photoshop

This is releated to a previous post I made, but I want to make it in a more refined way now.

When I double-click on a font texture in the Unity editor, it launches my default imaging application (Photoshop). Which is great! Unfortunately, Photoshop then balks at opening the file as it does not support the format.

Is there a way that I can get this to work, so that I can double-click the font texture in Unity, have it open in Photoshop, edit it there, then save it to (manually) reimport into Unity and use with the font material?

Alternatively, is there an imaging app that does recognize the Unity font texture format?

Take a screenshot of the generated texture and modify it in photoshop.
Then use the modified texture for the font material instead of the generated one.

But where can I get a screenshot of it in full res?

In the texture inspector.

I know I’m missing something obvious here, but in the Texture Inspector, I get a tiny little font map - way less than 512^2 or 1024^2 pixels.

In that case select the texture and choose: game object → create other → gui texture. This always created a full res, pixel correct gui texture, which you can screenshot in the game view.

Okay, I did that.

But the GUITexture it’s generating doesn’t appear to show all the fonts in the set or in the same configuration:

The texture contains all characters that you have access to in that font.

Seems like the game view is too small to view the entire texture, just make it large enough.
