I'm adding a feature to allow enable/disable of complex script features (bidi, complex char to glyph mapping) at runtime, using either (or both) command line option and config file element; the question I have is whether to enable or disable by default?
If enabled by default, those who don't use complex scripts or don't want advanced typography features in non-complex scripts will incur a minor performance penalty. If disabled by default, then those users who use complex scripts or want advanced typography features in non-complex scripts will need to do something special to enable this support. What does the group think? I don't have a strong preference either way. G.
