Twülpstedt, Normalisation of unicode strings
by Gerd Petermann 16 Nov '21

16 Nov '21

Hi all, see also https://forum.openstreetmap.org/viewtopic.php?id=74231 mkgmap sometimes fails to encode correct strings for a given codepage like 1252 (latin1). I've uploaded a file that contains an area in Germany where the u-umlaut in name Twülpstedt is encoded in two different ways, either with ü (0xfc) or as u + "COMBINING DIAERESIS" (0x75 + 0x308) See umlaut.osm at https://files.mkgmap.org.uk/detail/537 With the current code the 2nd variant is displayed as Twu?lpstedt. This 1-liner name = Normalizer.normalize(name, Normalizer.Form.NFC); helps to change the name to the usual encoding which works well with the codepage translation. So far so good. Now I wonder where exactly this call should be placed. My first idea was the code where the string is converted to a Garmin label, but maybe it should happen much earlier so that also the style rules "see" the normalized form. Any thoughts? Gerd

change mdr25 logic
by Gerd Petermann 16 Nov '21

16 Nov '21

Hi Ticker, attached are two slightly different patches for Mdr25 which I think make the code more plausible. v2 would be my choice. I've not yet tried to find out (again) how the sort works regarding strength. In my maps I see that Mdr25 contains fewer records than Mdr5 (e.g. 7609 of 8275 or 1146 of 1850), but I have no clue yet how to find out which recrods from Mdr5 are skipped, means, what exactly has to be compared.

Commit r4814: fix Mdr12 index position calculation for maps with mixed case labels
by svn commit 15 Nov '21

15 Nov '21

Version mkgmap-r4814 was committed by gerd on Mon, 15 Nov 2021 fix Mdr12 index position calculation for maps with mixed case labels Seems the position must refer to the first entry in Mdr11 that mmatches using PRIMARY strength. Alternative would be to stop writing this small section, but maybe it really helps on some devices http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4814

Problem with global index POI search
by Gerd Petermann 15 Nov '21

15 Nov '21

Hi devs, Enrico has contacted me in a PM about a rendering problem with his maps and while analysing that I found an obvious bug searching for e.g. "Scuola Dell Infanzia Fondazione Pietro Caprettini" as name of the POI without filling any further fiels in MapSource. When I start to type that name MapSource updates the list of candidates. For scuo it shows the full name "Scuola Dell Infanzia Fondazione Pietro Caprettini" but when I select that entry with the mouse the search returns "no items found" When I type scuol the name "Scuola Dell Infanzia Fondazione Pietro Caprettini" disappears from the candidates list as well as all other names starting with "Scuola dell". My understanding is that we probably create wrong Mdr11 entries, but MdrCheck doesn't complain. The tiles are at https://files.mkgmap.org.uk/detail/536 The command to reproduce the problem: java -jar mkgmap.jar --code-page=1252 --index --gmapi 66923003.img 66923005.img 66923006.img The tiles were created with the --lower-case option and a rather special style which sometimes adds leading / trailing blanks to names. It also produces lots of equally named POI. Gerd

Version mkgmap-r4813 was committed by steve on Mon, 08 Nov 2021 Format change to prevent error There was a line beginning with a '*' which is not meant to be a list and was causing a crash preventing the page being displayed on the website. Re-arranged the line so that it didn't start with the '*' http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4813
