3082, 4439, 7134, 8279 Various fixes for GEDCOM import.

Browse Source 
0003082: 1/4 and 1/2 ANSEL characters not supported on importing ANSEL
GEDCOM
0004439: [Info]: characters ignored on a Gedcom encoded ANSI (cp1252
West Europe, USA)
0007134: Failure importing ANSEL encoded gedcom file.
0008279: GEDCOM import fails for ANSI file incorrectly opened with the
utf8 locale

Fixed GEDCOM import not working properly for Python3; other problems
also corected, including fixing the inability to import Windows CP1252
coded files. Also more consistent fix for 8014. Ensured any error
messages are not lost. Fixed a few ANSEL characters that were not
translated.
