IllegalArgumentException: Only chars are supported

Hi,

I am using Locus Map Classic. Since yesterday I have a problem when downloading or updating geocaches. Often (not always) I get an IllegalArgumentException because only chars are supported (see attached picture). I would assume that this has to do with special characters (like emojis) in the cache title.

My impression is that this is mainly a problem on Groundspeak API side. Probably I will just have to wait a few days and they have fixed it. However, I could not find any information anywhere. So I thought I bring this to your attention.

Repro steps:
set marker somewhere
choose download geocaches in your area
if you do not get the error try it somewhere else

Best regards,
Thomas.
