Steve, digging through your code a little, I stumbled upon the forceUppercase() method and traced its initialzation back to the --lower-case command line option. I had the impression that this option was considered useless, but I tried it nevertheless to see for myself: on the contrary! Perhaps for the first time ever, I see a proper “ß” on a Garmin. Since until only recently¹ this German character did not have any upper case counterpart, it could only be transliterated to SS and so I always see streets ending in -strasse instead of -straße everywhere on Garmins. It always feels like Swiss German (who abandoned the ß long ago). ¹ http://en.wikipedia.org/wiki/Capital_%E1%BA%9E
The micro sign U+00B5 μ becomes a ? on most code page maps, except for the Greek one, even though it is at the same position in all code pages.
U+00b5 is upper cased to GREEK CAPITAL LETTER MU, which is only present in the Greek code page.
With --lower-case, I now also get the μ micro sign all over, not just in the Greek code page. I guess … --code-page=1250 --lower-case … will become my favorite options. ;-)
And in the Arabic map’s upper half, the latin based characters show up as “?”.
That's because only lower case characters are included.
With --lower-case, the accented latin characters work fine in the Arabic map. Given these results, I’d like to ask you to reconsider your proposed action to remove the --lower-case option and code. http://wiki.openstreetmap.org/wiki/Mkgmap/dev/option-review I got the impression that it _does_ work, and I enjoy the effect very much so far.
Another peculiar thing: while the Garmin does its usual wierd upper/lower casing, TWO LABELS ARE ALL CAPS, namely those containing the ª feminine and º masculine ordinal indicators.
I don't know about this. Possibly a device thing?
I guess I’ve got a lead on this. With --lower-case, the input label “62 0062 b LATIN SMALL LETTER B” shows up the same on the Garmin, whereas the input label “42 0042 B LATIN CAPITAL LETTER B” shows up as “42 0042 B Latin Capital Letter B” on the Garmin, i.e. partially lower-cased. My theory: • when the Garmin sees all upper case characters in a label, it folds the case into title caps style • when the Garmin sees a lower case character in a label, it leaves the label characters’ case as-is. With this theory, it probably considered the ª and º characters as lower case. rj
