    Is there a convention for how to encode these "alternative glyphs"?

    By sticking to Unicode we have the ability in ODF to easily exchange text content with anyone else that understands Unicode.  So transformation to HTML is easy, indexing by search engines is easy, etc.  

    If we layer on an additional encoding mechanism on top of Unicode, I'd want to make sure that the things that are easy today remain easy.

    For example, most of the text in an ODF document is content like this:

    <p>hello world</p>

    We could annotate a character with an alternative glyph through some ad-hoc escape mechanism:

    <p>hello w##27orld</p>

    Or we could introduce a character element to provide additional attributes at a character level:

    <p>hello <c altGlyph="27">w</c>orld<p>

    Either method makes it more complicated for doing simple operations on the text.  This also seems very font-specific.  So a document created on Windows with one font and then displayed on Linux with a fall-back font will probably not be able to use the same alternative glyph.  In fact, their rendering may look incorrect if they try.

    Are there any XML markups that currently support alternative glyphs?  How do they do it?

    There is EGIX, but I don't have idea how widely is adopted:

    Interesting.  I wonder if this could be be treated as part of the style, not as part of the content? So, "I want 12-point Times Roman, bold, with alternative glyph 27", but the content.xml knows nothing about the alternative glyph.  That is a way we could do this in a way which does not break compatibility with older processors.

    I could not help saying, this seems a wonderful solution.
