PowerShell pipe default OutputEncoding should match [System.Console]::OutputEncoding to avoid encoding issues with native console tools like `more`

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

When executing commands like:
echo 中文文本 | more
the output is garbled (涓枃鏂囨湰) because PowerShell's default $OutputEncoding is UTF-8, but native Windows console tools expect the console encoding (e.g. GB2312).
To improve compatibility, it is recommended that PowerShell by default sets:
$OutputEncoding = [System.Console]::OutputEncoding
unless the user explicitly overrides it. Because after executing $OutputEncoding = [System.Console]::OutputEncoding, commands like echo 中文文本 | more work correctly without garbled output.
This change would prevent common encoding mismatches in pipelines and improve interoperability with native Windows console tools.

Expected behavior

echo 中文文本 | more
中文文本

Actual behavior

echo 中文文本 | more

Visuals

Reproduce the issue on Windows with echo 中文文本 | more, then trace how the pipeline uses $OutputEncoding and how [System.Console]::OutputEncoding is obtained. The work is done when the default behavior produces readable native-console output without overriding $OutputEncoding, while explicit overrides continue to work.
