The console output codepage is adjusted depending on the encoding used in PHP. Depending on the concrete system OEM codepage, the visible output might or might be not correct. For example, in the default cmd.exe and on a system with the OEM codepage 437, outputs in codepages 1251, 1252, 1253 and some others can be shown correctly when using UTF-8. On the same system, chars in codepage like 20932 probably won't be shown correctly. This refers to the particular system rules for codepage, font compatibility and the particular console program used. PHP automatically sets the console codepage according to the encoding rules from php.ini. Using alternative consoles instead of cmd.exe directly might bring better experience in some cases.
