I finally figured it out. I decided to send numbers through the network and then on a client convert them to the chars.
If anyone will have that problem:
First of all I’ve created this in “h” file of the GameInstance.
In “cpp” file of the GameInstance I’ve created (also at the top you should include string):
(Big thanks for that to a guy from 2019)
UE has that function “Get character as number” that converts character to int (in utf32 I guess)
I add all numbers to extra settings.
Then on the client I convert all of the numbers to chars using the new function.
Works really well for me!
After changes you have to build the project (UE editor should be closed and there should be no running process UE. Sometimes it’s ON even if the editor is closed)
