[mkgmap-dev] MapSource special behaviour with Chinese characters (unicode)

Wed Dec 1 15:31:29 GMT 2021

Hi Ticker,

yes, something like that might happen. I don't say something is missing, the opposite: I get too many matches.
I used my patch, so maybe the results are a bit different with trunk.

My Oregon seems not even able to display the chinese characters, so I cannot check anything with it.

Anyway, compared to r4808 the search works much better, at least on MapSource.

Gerd

Hi Gerd

Our unicode sort is known to be incomplete and this incompleteness is
probably reflected in the SRT subfile. MapSource might try and use this
to effectively reproduce the Mdr section we don't write for unicode and
this could make lots of names look identical and hence not to be shown
in the street selection list.
