    CLDR, and ICU, has (some) support for that. See

    The data in these datafiles are used by the RBNF number formatter
    and reader APIs in ICU:
    (None of them permit substituting "numerically equivalent" Han characters
    for reading.)

    More on numbering systems in CLDR: see
    Systems.xml. One, just one (for now at least), decimal-base position system
    using Han characters is supported, called "hanidec". The names listed in
    numberingSystems.xml can be used in the ICU API to ask for the numbering
    system in question. (Some of the number spellout systems, including the
    Han character ones, can be asked for that way; but most cannot, and one must
    then use the RBNF API directly.)
