Hi,

the beta reports a nil value for "getsubtype", fix below.

if not direct.is_glyph then
    local getchar    = direct.getchar
    local getid      = direct.getid
    local getfont    = direct.getfont
+   local getsubtype = direct.getsubtype
    local glyph_code = nodes.nodecodes.glyph
    function direct.is_glyph(n,f)
        local id   = getid(n)
        if id == glyph_code then
            if f and getfont(n) == f then
                return getchar(n)
            else
                return false
            end
        else
            return nil, id
        end
    end
    function direct.is_char(n,f)
        local id = getid(n)
        if id == glyph_code then
            if getsubtype(n) >= 256 then
                return false
            elseif f and getfont(n) == f then
                return getchar(n)
            else
                return false
            end
        else
            return nil, id
        end
    end
end
