Hi all, recently I learned about this feature which is already partly implemented in mkgmap, but not easy to use with OSM data. See http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2017q2/026602.html There is at least one visible effect of these 0x1e and 0x1f characters: When you zoom out MapSource removes the prefix / suffix part(s) from the name. So "Rue de la Concorde" is displayed as "Concorde" which requires less space and probably allows to display more names. If I got that right the prefixes and suffixes are also excluded from the index by mkgmap, but that might not yet work.
My understanding is that we need a way to change the a road label "Rue de la Concorde" to "Rue de la" + 0x1e +"Concorde" or "Fernrodder Strasse" to "Fernrodder" + 0x1f + "Strasse". Does anybody already use that feature in style rules? I can think of several ways to implement that. 1) A collection of style rules for well known prefixes and suffixes. I fear those would be quite complex. 2) A new option file listing prefixes and suffixes and some Java code to modify all road labels. Format of the file might be prefix=Rue de la prefix=Rue du prefix=Rue de prefix=Rue prefix=Rua prefix=Chemin de la prefix=Chemin du prefix=Chemin de prefix=Chemin ... suffix=Road suffix=Steet suffix=Strasse suffix=Weg ... I assume it is possible to compile a single regular expression from this, so performance should not be a problem.
