[mkgmap-dev] Commit r4820: Modify default encoder (code-page=0)

Version mkgmap-r4820 was committed by gerd on Tue, 30 Nov 2021 Modify default encoder (code-page=0) format6-v6.patch by Ticker Berkin. Original description for the first version of the patch: "I was looking at encoders and noticed obvious mistake in Format6Decoder relating to lower-case, plus parts that can be simplified to be general and consistent with Format6Encoder. Format6Encoder can handle a bunch of other characters (the remains of the 'ascii' printables) + lower-case - I've implemented these." http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4820
