Hi, a local definition for numbers has to be added to get language dependant settings to \definebreakpoint. function breakpoints.handler(head)     local done    = false     local attr    = nil     local map     = nil     local current = head     while current do         local char, id = isglyph(current)         if char then          -- local a = getattr(current,a_breakpoints)             local a = takeattr(current,a_breakpoints)             if a and a > 0 then                 if a ~= attr then                     local data = mapping[a]                     if data then                         map = data.characters                     else                         map = nil                     end                     attr = a                 end                 if map then                     local cmap = map[char]                     if cmap then                      -- setattr(current,a_breakpoints,unsetvalue) -- should not be needed                         -- for now we collect but when found ok we can move the handler here                         -- although it saves nothing in terms of performance                         local lang    = getlang(current) +                       local numbers = languages.numbers                         local smap    = lang and lang >= 0 and lang < 0x7FFF and (cmap[numbers[lang]] or cmap[""])                         if smap then Wolfgang
