My friend, who owns a Garmin GPSMap 60CSx, notified me of a character set problem in a tile name of my map. I wasn't aware of the problem, because my Edge 705 does not display map tile names. The tile Etelä-Suomi (Southern Finland) appears as Etelä-Suomi, where the currency symbol ¤ is displayed as a black diamond. Other ä characters in the gmapsupp.img are encoded as the byte code 304 in octal notation. The workaround should be simple: in mkgmap.args, write the ä as \304 instead of using UTF-8. But I would except the parameter to be translated. After all, the style files are already interpreted as UTF-8. I think that the right fix of this bug would be such that \u escape codes are expanded before utf-8 to target character set translation, and hex and octal escape codes (\xC4, \304) are expanded after the translation. That would also allow us to embed Garmin control characters where desired. Also, I would like to have some transliteration in the UTF-8 to cp1252 (latin1) translation. The Garmin displays many latin1 and cp1252 code points as a black diamond, as I posted some time ago. We could avoid that by translating those code points. I attempted to override the built-in translation (in the JRE as far as I understood) some time ago, but I must have patched the wrong place, because my changes had no effect. Any hints, Steve?
