    unicode: reduce the size of utf8data[] · a8384c68
    Olaf Weber authored
    Remove the Hangul decompositions from the utf8data trie, and do
    algorithmic decomposition to calculate them on the fly. To store the
    decomposition the caller of utf8lookup()/utf8nlookup() must provide a
    12-byte buffer, which is used to synthesize a leaf with the
    decomposition. This significantly reduces the size of the utf8data[]
    array.
