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.
I see that you've already committed this change. Thanks, I'll try it and let you know.
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:)?
GroundTruth's MP files are UTF-8 encoded, but "national" non-ASCII characters are converted to similar ASCII chars (using an OSM Wiki table), so I'm not sure which character would be problematic in this case. I also set the following polish parameters by default: CodePage = 1250 LBLcoding = 9 I'll try to experiment with some smaller MP file. Regards, Igor
