| Description: |
String length parameters to several C functions are documented (in both 8.6 and 9.0) as *If the length is negative, the encoding-specific length of the string is used.* While 8.6 correctly checked for negative lengths as `(srcLen < 0)`, this has been changed in 9.0 to `(srcLen == TCL_INDEX_NONE)`. Aside from changing the **documented** semantics, this also has resulted in the functions not handling the case of negative values other than -1. The checks should be reverted back to checking for negative values as opposed to checking for `TCL_INDEX_NONE`. | |||
