    Actually you misinterpreted what i said.

    pseudo unicode is a term used to describe non-Unicode legacy glyph
    based encodings that are superimposed over Unicode blocks. to the
    average application it looks like Unicode but isn't Unicode.

    For the Myanmar script examples of pseudo-Unicode would include the
    zawgyi and ayar fonts.

    For languages like Burmese pseudo-Unicode content is much more common
    than Unicode content. And all mobile solutions I've seen for Burmese
    have been non-Unicode.

    That is what i would term transcoding, and not what i mean by pseudo-Unicode.
