[mkgmap-dev] MDR and city streets on different tile from POI place=city

Wed Nov 3 10:40:00 GMT 2021

Hi Gerd

The scenario is:
 --lower-case,
 2 tiles,
 mkmap:city "Aa" area that spans the tiles",
 streets with this mkgmap:city in either/both tiles,
 the City POI "Aa" on one of the tiles,
 another city, eg "AA" in the tile without the "Aa" POI,
 streets for this.

I am finding streets in the tile with both regions are all assigned to
one or the other and this behaviour is effected by the presence of the
City POI.

PlacesFile::CreateCity(not unique) will return the same City record for
both "Aa" and "AA" so I propose to remove the toUpperCase() from it
when --lower-case (unless ascii/cp0 which forces upper case)
