Front-end is ready? Is ENCODING="UTF-8" related to UCS-4 support? Because if it is, then the front-end is not ready, it only supports a single character kind.

We are not required to support UTF-8 strings as a character kind (that would be really hard) but just UCS-4 strings (ie UTF-32), which is basically (as I see it): - remove limitations in the front-end that there is only one character kind] - make a new character kind, as an array of 32-bit integers and a length - adjust library functions Then, I/O with UTF-8 encoding just needs UTF-8 <--> UTF-32 conversions, which is only a few dozen lines of code (unless I'm confused). -- fxcoudert at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |fxcoudert at gcc dot gnu dot | |org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35863
