Vadim Zeitlin 81fb185e4f Fix setting the fonts for wxMSW wxTextCtrl with wxTE_RICH(2) style.
Using WM_SETFONT seemed to work with rich edit controls but in fact it
doesn't, it only changes the font used by the control initially apparently but
it can be reset later.

Use EM_SETCHARFORMAT which is more reliable.
