One, two, three hours extra for processing all of Europe, Africa, Asia and Oceania is not a problem for weekly updates.
Ehhh. In 3:20 the windows console version can handle a half GB file. (only copiing takes 2 minutes and twenty seconds). So for 80 GB that would be more than nine hours. Or is this a wrong calculation? Maybe it has to be done in this way: Handling time for 0.5 GB 1 min (3:20 - 2:20). So 80GB 160 min == more than 2 and the half hour. Reading/writing 7.3 GB one hour. Together three and a half hour. Add some time for uncompressing/compressing.

..The whole point with mkgmap and converting from one code tabel to the other is that it places a questionmark '?' if it cannot find a match. If it would just place one byte from the two bytes that it had to convert than it would do much better.
Ha.. not two bytes. UTF-8 is multibyte (from one to six) just read the rfc 2279.

From multibyte the conversion will -usually- first go to two byte unicode followed by a conversion to one byte ansi.
