Subject: Fix wxStyledTextCtrl compilation in non-Unicode build.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/d7b468788e860e7e39bb55bb921f757207b6f9fe

Fix wxStyledTextCtrl compilation in non-Unicode build.

The value returned by wx2stc() in non-Unicode build is a simple "char*" and we
can't call length() method on it, add a helper wx2stclen() function to get the
length from the original wxString itself in this case.

Closes #14013.
