[mkgmap-dev] [mkgmap-svn] Commit r4810: revert changes from r4809 for now, they caused more trouble

Thu Nov 4 10:55:37 GMT 2021

Hi Gerd

Here is a minimal patch to stop the 2 assertion crashes:
1/ unspecified sort for some blocks of Unicode chararacters.
2/ inconsistent MDR20 city positions that could result from city names
   with different case or use of non-unicode multi-byte codepage

For 2/ with option --lower-case, the behaviour of how and which cities
with capitalisation differences are shown in the find list, and which
streets are attached to them is: 
1/ device/BaseCamp/MapSource dependant.
2/ depends on how the streets are spread over tiles where there is
   possible name conflict.
3/ Affected by the presence of city POI on a tile. 

Ticker
