When listing a large document containing Unicode, the SSH glyph cache experience so many misses that it's actually making rendering much less efficient.
Considering that the glyph cache has relatively low savings for Latin text, we should probably do one of the following (for now):
1. Expand the glyph cache such that it can contain many more characters (enough that CJK rendering is efficient)
2. Disable the glyph cache within SSH entirely
3. Restrict the glyph cache to Latin characters
