[4692 win] TT Hinting broken

[Luc[as]]

TT hinting does not work when "[v] use custom [cmap] encoding" is switched on, doesn't make any sense does it?

[Adam Twardoch (FontLab)]

Indeed it doesn't.

I would advise not using the "Use custom cmap encoding" option. We added it to FontLab Studio 5 but now consider it deprecated. Rewriting the "cmap" table into some custom stuff should be done on a post-processing level, using tools such as DTL OTMaster or ttx.

[Luc[as]]

Huh? You mean that even though FontLab has an interface for this job we shouldn't use it and do it by hand in another tool? Can you explain why? Is FontLab doing it wrong?

Anyway, I am not writing the "cmap" table into some custom stuff, but just add a standard cmap this way which is needed to make TTF fonts run on Macs as well.

[Adam Twardoch (FontLab)]

1. Which cmaps are you adding? 1.0? 0.3? Any other?

2. Does the default FLS behavior produce TTFs which are in some way no good for Mac OS X? Could you please elaborate why you need the custom cmap setting?

Thanks,
Adam
