Help generating CID fonts

Hey everyone,

I have a client asking about having a licensed font delivered instead as a CID font, as they are running a piece of old software that requires an Identity H Encoded CID font.

Since CID fonts contain 16-bit glyph sets like Unicode, is there any simple way of converted already mastered .otf/.ttf files to a CID font? Or does this need to be done at an earlier stage in the mastering process?

If the latter, is there any way to insure my font that is being generated from Fontlab 5 will be a CID/Identity H Encoded font? 

My understanding is that Big-5 and Shift-JIS based encoding for Chinese and Japanese will be CID fonts, but is there any Western/Latin codepages that will create a CID font?

Thanks!
