Summary ------- Configure UTF-8 native-pipe output for PowerShell commands launched by the Buzz MCP shell. Fixes: ------ - block#5070 - block#6527 Problem ------- Windows PowerShell encodes text sent to native processes as US-ASCII. As result, PowerShell replaces all non-ASCII message characters messages sent by agents when the message is piped from PowerShell to buzz: ```ps1 ... | buzz messages send --content - ``` For details, see - block#6527 Solution -------- Prepend a UTF8Encoding OutputEncoding assignment when the resolved shell is powershell.exe or pwsh.exe. Git Bash and other shells retain their existing command text. Add a regression test for both paths. Signed-off-by: Bernhard Kaindl <bernhardkaindl7@gmail.com>
