We store character-map records for font character coverage in the shared font list Face entries, to avoid needing separate per-process copies of them. But I notice that when we instantiate a new gfxFontEntry for a face, the code fails to check if there is already a character map stored for it, and so we may redundantly re-read the cmap table. We shouldn't do that.
