OSM and Japanese characters
Quote:
Sam, you seem to be "in the loop" with MkGMap. Can you tell me when/if they will ever fix the problem for Japan where place names are all transliterated into Latin characters with CHINESE readings. While many of the characters are the same, the readings are completely different. For example, what should be "Keihin-Kyuko" becomes "Jingbangjixingxian" (or something like that). I pointed it out years ago, but nobody seemed to be interested in fixing it...

Hi Chris...
It's not really a thread I've been following, but I did find this on the MkGMap wiki and it does seem to parallel my vague recollection of the discussion regarding Cyrillic characters that I was following for a while.
When MkGMap is executed, you may specify numerous options within the command line. One of those options specifies which code page (character set) the program should use when generating the img file. From what I see, code page 932 (Japanese characters) is now supported. It also appears, however, that the Garmin device must have the font installed. The wiki above does have a good link and intructions as to how to install the fonts on an older Nuvi. I'd check out the Garmin site to see if your model supports the character set natively or just what you have to do to get the Japanese character set to display.
The rub is to have an img file created using the --code-page=932 option set. I'd guess that most of the pre-made ones (like those on Lambertus' excellent site) are set to the default Latin. Although, it might just be worth a quick note to him to see if he would be willing to offer the option for Japan...
It is possible to generate your own img file using OSM data and MkGMap with whatever options you want, but it is not a quick and easy job or for those who are hardware-challenged. The data set for the entire planet now runs about 20G, although sub-sets are available. And it does take a machine with lots of memory. I've done it successfully for maps of BC, (but just barely) using a Linux machine (the way to go for this) with only 4G of memory. It took a few hours to generate the img file. Downloading from Lambertus is so much easier!
Anyway, I'm no real expert on this. Just an interested bystander. I think I'd take the easy route first by contacting Lambertus and asking about him offering the option of Japan with a 932 codepage and if that doesn't work, maybe ask the MkGMap folks if there are any problems to watch out for when generating your own. Then, if all is OK... maybe give that a try.
