Some TTF / OTF fonts not working in the new graph API renderer

I downloaded the play fonts from here http://www.fontsquirrel.com/fonts/play in TTF format.

The bold one works fine, but the regular one can't find any glyphs when trying to draw:

 java.lang.RuntimeException: Could not retrieve glyph for symbol: <T> 84 -> glyph id 0
        at jogamp.graph.font.typecast.TypecastFont.getGlyph(TypecastFont.java:200)

        at com.jogamp.graph.curve.opengl.TextRegionUtil.drawString3D(TextRegionUtil.java:182)

I tried converting it to OTF format using online converters, then realised none of my OTF fonts work - they can't be loaded at all:
java.lang.NegativeArraySizeException

Another problem with some fonts, for example Armata-Regular from Google Fonts: http://www.google.com/fonts#UsePlace:use/Collection:Armata (download in top right corner) - whichever text I try to render, I get square characters instead of real text.

Is there anything I'm doing wrong? Is there a specific Font converter to make sure they work in Jogl?

Seems we have an OTF bug in typecast .. hmm.
Pls file a bug report, even though this will have lowest prio for now.

That seems to be a UTF/glyph-index issue then, maybe another bug report.

Please make both new bugs depend on the existing font holding bug:
