Subject: use const wxMBConv& instead of wxMBConv& in public methods so that it's possible... 
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/5487ff0f501619e1b87e8a1f2c03bcc4a87ef375

use const wxMBConv& instead of wxMBConv& in public methods so that it's possible to pass in temporary objects;
don't use global wxConvUTF8 object internally, it may be unavailable at static objects destruction time
