Re: Plea for minimal tagbits

Hrvoje> 31-bit integers are nice, but they are hardly that Hrvoje> important to a normal user. But when Olivier gets his UCS-4 text manipulation stuff working.... Although extremely few users will want to use UCS-4 for itself, the least buggy quick path to a wide-char Mule in multilingual contexts uses UCS-4 in the implementation. UCS-4 characters, by a strange coincidence, just barely fit into a 31-bit integer. Unifying the Han ideographs through UCS-2/Unicode is possible, but will surely introduce new coding-system I/O bugs. The UCS-4 approach will allow us to change the current low-level buffer implementation with minimal impact on higher-level Mule code by preserving the coding-system information at the character level as the current Mule implementation does. I think there's a pretty good argument here for pushing at least for Mule builds to get minimal tagbits by default, maybe not for 21.x, but soon.
