[XeTeX] question about ScriptPercentScaleDown

[Antonis Tsolomitis]

Hello,

I am not sure if this is the correct list for such a question... if not,
I would be glad if someone can direct me to the correct list.

I am developing a Math Table for a font (to be released with OFL
license) and I have a
difficulty with the parameters ScriptPercentScaleDown and
ScriptScriptPercentScaleDown.

If I do not set any point size in the documentclass (so it defaults to 10pt)
everything works fine.

But if I set the 11pt or the 12pt option, xelatex (as well as lualatex) ignore the
ScriptPercentScaleDown and ScriptScriptPercentScaleDown
parameters and default to 80% and 60% respectively.

Do I miss something here or have I hit a bug..., maybe?

Let me also mention that I just checked with Asana-Math and the behavior is the same.

Thanks for any hint,

Antonis.
