Ezio and Alexander: after reading your posts and looking back on my code: you're absolutely right.  Doing resize(31) is pointless: it doesn't save space (mempool serves [8],16,24,32 there; and: dynamic, normalized coded names don't exist that long in real life, too).  And append_char() is inlined but much more expensive than doing (register-loaded) *(target++)=char.  Thus i now do believe my code is a bug and i will rewrite doing *target=cstr(resize(len(input)*2)) ... truncate() instead!
Thanks.
