Core/Misc: Fixed utf8 encoding in console input/output. (#26352)

* Core/Misc: Fixed utf8 encoding in console input/output.

* Fix gcc build

* Fixed that weird 'a' with circle above it and other similar letters. Also fixed encoding in AppenderConsole which sometimes did not work as it should

* Fix build on Linux

* Probably better to do it like this
