I don't think it is suitable to include info on how well each each curve formats are rendered - such text belong at the various renderers (most notably libfreetype, but maybe also libSDL and others), and vary as those renderers evolve and with how they are used.

They are supposed to provide the same typographical features, except for the underlying CFF and TTF glyph formats. I'm about to add this paragraph to 'fonts-thai-tlwg' package description: Every font in this package is provided in TrueType and OpenType formats for users to choose to suit their needs. Both formats are maintained to provide the same glyph set, glyph design, and typographical features, except that curves and hints are defined in CFF format for the OpenType version, and in TTF format for the TrueType version. Do you think it's sufficient? Or should I try to evaluate the current quality of both formats as rendered by FreeType? To my personal taste, the OpenType version used to be inferior, until the FreeType CFF rendering improvement was contributed by Adobe. And now I prefer the OpenType version personally. The TrueType hinting, however, is based purely on FontForge auto-instruction, no manual tuning.

Source: fonts-tlwg Version: 1:0.7.2-1 Severity: normal -BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi, fonts-tlwg are provided as both Truetype and Opentype, but package descriptions lack any mention of when either format is more suitable. Maybe Truetype fonts include hinting omitted from Opentype fonts. Maybe Opentype fonts include feature sets lacking in Truetype fonts. Maybe they are technically equal but consuming applications vary in their support for accessing all features of either format.
