• File win/tclWinPipe.c — part of check-in [2de1551609] at 2016-08-30 13:07:10 on branch trunk — Don't ever allow UTF-8 sequences of more than 4 characters to be generated or parsed, even when TCL_UTF_MAX>4: According to current Unicode standard, a byte string of >4 characters can never form a single UTF-8 character. And a few minor micro-optimizations related to UTF-8 handling. (user: jan.nijtmans size: 84278) [more...]
