How I can decode TIdMessage from koi8-r to windows-1251?
#1
I use Embarcadero C++Builder 10.2 Tokyo with Indy 10.
The task is to check emails via POP3. I can get emails, but I don't know how to decode their subjects, attachment file name, etc from koi8-r to windows-1251 or UTF-8.
Can anybody help me?
