Changes

  1. Change assignee to "nobody"
  2. Change closer to "nobody"
  3. Change cmimetype to "text/plain"
  4. Change comment to:

    tcl.h has:

    #if TCL_UTF_MAX > 4 /* * unsigned int isn't 100% accurate as it should be a strict 4-byte value * (perhaps wchar_t). 64-bit systems may have troubles. The size of this * value must be reflected correctly in regcustom.h and * in tclEncoding.c. * XXX: Tcl is currently UCS-2 and planning UTF-16 for the Unicode * XXX: string rep that Tcl_UniChar represents. Changing the size * XXX: of Tcl_UniChar is /not/ supported. */ typedef unsigned int Tcl_UniChar; #else typedef unsigned short Tcl_UniChar; #endif

    (See in context here: http://core.tcl.tk/tcl/artifact/f555d5aa61ea46ec31d833b33c52fb8788c8dcdf?ln=2208-2221)

    That means, with TCL_UTF_MAX 4 Tcl_UniChar is still an unsigned short. This is obviously wrong, because a valid 4 byte utf-8 char is beyond the BMP, that means bigger than an unsigned short.

    That define should read as

    #if TCL_UTF_MAX > 3
