There was an issue in the maximum_color tool that affected BungeeSpice-Regular.ttf, see https://github.com/googlefonts/nanoemoji/issues/427
Here I took the original BungeeSpice from upstream djrrb repository and run it through the latest maximum_color (v0.14.3).
The font has the (colored) .notdef glyph at index 0, and space character is again mapped to 0x20 in cmap as it should be. The space was currently un-cmapped (for it had been moved to index 0) and thus as-if missing.
* Add language support metadata to the OFL families.
* Add language support metadata to all apache/ufl fonts.
* Add language support metadata / sample text to remaining OFL families.
