The test was intended to verify that round trip via wxFile::Write/Read() worked even for the strings with embedded NULs but as the string wasn't constructed correctly it didn't actually contain any NULs but was ended by the first of them. Fix this by using explicit length of the string as usual when dealing with strings with embedded NULs. Also fix the conversion back to Unicode to use the correct length. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65835 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
