1) Other than the lack of support for most OpenType layout and substitution features, what are the special considerations for making sure fonts work well in MS Office on Windows? For instance, is there any weird behavior around vertical metrics, naming, etc.

2) While some foundries sell "office" versions of their fonts, my impression is that these are basically the same as the regular OTFs but with the character set arranged differentl (e.g. lining figures in the default position, small caps in a separate file). Is that correct, or are there other common optimizations for these fonts?
