Keil 5.27 "Windows 1251"

Hello!
We have a problem using the new Keil v5.27.1. The new editor does not allow you to print characters in Windows 1251 encoding. Before that, Keil v 5.24 a was used and there were no problems with it.
Using UTF-8 encoding will not help us, because our projects use a lot of string variables in the encoding "Windows 1251".
I really hope for Your help. Thank you!
