[mkgmap-dev] Commit r4432: utf8-v3.patch by Ticker Berkin

Version mkgmap-r4432 was committed by gerd on Mon, 27 Jan 2020 utf8-v3.patch by Ticker Berkin - uses StandardCharsets.* where possible. - notes some usage of the java local DefaultCharset. - changed a couple of these to force utf-8 instead. - if --read-config file gives decoding errors, names the charset used to read the file (ie DefaultCharset) instead of 'utf-8' in the error message. - accepts/ignores unicode BOM in more files - uses try (open...) {} where possible in files changed for the above reasons. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4432
