    The values for Registry, Ordering, and Supplement fields
    in the CIDSystemInfo dictionary in the font desctiptor are
    arbitrary - there are no constraints on it. However,
    the only four character collections recognized by Acrobat
    are Adobe CJK sets: Adobe-GB1, Adobe-CNS1,
    Adobe-Japan1, and Adobe-Korea1. This implementation
    limit effectively narrows the scope of unembedded CID
    fonts: they can only be used for CJK characters. There is no
    standard character collection to represent e.g. Cyrillic
    or Hebrew.

    I could not find one, despite browsing Adobe documentation
    very thoroughly. Perhaps you will be more lucky :-).
    However, I believe that the best thing would be to obtain
    Type1 equivalents of OpenType fonts - this would greatly
    facilitate the process.

    Subject: RE: [xep-support] Problem embedding Adobe OpenType Fonts, need help please.

    What Adobe specifications are you refering to with regard to the adobe-*
    attributes? I understand that the values are determined by Adobe, but
    don't know where to find the values for a given OpenType font. Is there
    a tool that reports these values for the font, or are they published in
    some document?

    Is anyone aware of a work-around for this limitation of XEP? Is it
    possible to convert an OpenType font to be a TrueType font so it can be
    embedded in the PDF?

    Is there any word on when XEP will support emdedding of OpenType fonts?
    If there is no known work-around then this would be a very important
    feature to include, hopefully soon!

    Many thanks

    -- Bennett

    Hello Bennett,

    You have 'embed="true"' in your font configuration, but XEP cannot embed
    OpenType font thus it issues a warning. XEP limitations regarding
    TrueType/OpenType fonts are listed in section 5.1. "TrueType and
    OpenType Fonts" of "XEP 3.6 User Guide" (userguide.pdf). As for
    'adobe-*' attributes - their values are determined by Adobe ad hoc for
    each character collection; please refer to Adobe's specifications.

    BS> Hello,

    BS> I have the XEP 3.6.3 client and am trying to follow the steps to
    BS> configure support for some additional Adobe OpenType fonts I have.
    BS> The fonts are part of the "Adobe Type Basics OpenType Ed."
    BS> collection. Following the instructions in the manual I added some
    BS> additional lines to the fonts.xml file. Here is an example of the
    BS> additional font lines I have added:

    BS> <font name="AGaramondPro-Regular"
    BS> ttf="C:/PSFONTS/AGaramondPro-Regular.otf"
    BS> adobe-encoding="UniCNS-UCS2-H"
    BS> adobe-ordering="CNS1"
    BS> adobe-supplement="1"
    BS> embed="true">
    BS> <alias name="AGaramondPro"/>
    BS> </font>

    BS> When I convert a .fo file to .pdf the conversion seems to be working
