A hidden iconv error

[blackyhn]

Hello,
I'm having a crash in production.
I guess it is related to the iOS 17.1 upgrade.

Im having this in my crashlog:

10 TestApp 0x0000000103d73ce0 charconv_buffer + 160 (charconv.c:268)

So I guess iconv is behaving not as expected.
I spoted some other threads on the net related to this issue like:

Can you please help me understand what is going on ?
Thanks!
