I'm trying to generate Garmin maps files from Polish maps generated by GroundTruth. I get the following exception (using the latest version of mkgmap):
SEVERE (PolishMapDataSource): error decoding label java.nio.charset.UnmappableCharacterException: Input length = 1
This is caused by a character in the input that cannot be represented in the target character set. Instead of throwing an error when this happens I will change the code so that it just replaces the character with a '?' character. There is also the problem with the character set and encoding used to write the input .mp file. We have changed the code in mkgmap a number of times to try and match commonly found .mp files. Currently we read .mp files as though they are in utf-8 and then convert into the target codepage. This is common for OSM derived files, since the names are in utf-8 to begin with, but I don't know if this is true in general or recommened. Are the labels written by GroundTruth in utf-8, or are they already converted into the target codepage (or something else:)? Regards, ..Steve
