--- Comment #6 from Orvid King <[email protected]> --- Perhaps it would be possible to simulate a character set cache by using a template to represent the set of characters included? For the runtime version, is there any real reason to force the charset cache to be thread local? Could it perhaps be global with dirty read and a possible re-calculation? >From my experience, most nievely implemented caching mechanisms fail to understand that a best-effort cache is usually more than enough. --
