| Description: |
Just opening the case in tcl upstream, to be aware of the problem: https://github.com/SWI-Prolog/packages-xpce/issues/2 The chr type is 16bit, hence the maximum range size is limited to 2^16, which is not sufficient to trigger the overflow. Note that TCL can be built with 32bit chr type depending on the value of TCL_UTF_MAX macro. The default value is 3, which implies the use of 16bit chr. Other valid value is 6, but that is considered experimental upstream and not recommended. | |||
