Description
I stumbled upon the following minor issue regarding fonts in libGDX 1.6.5:
I created a bitmap font file with Hiero where 0 and O happen to be pixel identical. It seems to be a feature of the fnt format to not include these glyphs twice in that case. The loader of BitmapFont does not recognize this optimization and therefore 0 characters are not rendered.

Research direction
Start by inspecting the BitmapFont loader and the Hiero-generated .fnt format described in the report. Reproduce a font where 0 and O are pixel-identical, then verify that both characters render correctly when the loader handles the format's glyph optimization.
