[mkgmap-dev] [mkgmap-svn] Commit r4811: fix java.lang.AssertionError while building index from unicode tiles

Thu Nov 18 16:24:01 GMT 2021

Hi Ticker,

please help me: I don't want to change the source. What unicode code character is ignored? How do I find one?
My understanding is that I need an input file with 255 cities and then one additional city which has the same name as one in the map and an appended ignored character.

Gerd

Hi Gerd

Sort and Collator with lots of ignored characters did it for me.
The new assert in Mdr29 is there to detect problems before the getting
to the stage where Mdr25 ptr needs more bytes than Mdr5 ptr.
