PowerShell.MCP v1.2.7 - Intelligent Encoding Management and Localized MCP Prompts

Intelligent Encoding Management and Localized MCP Prompts

This release introduces intelligent encoding management that automatically upgrades ASCII files when adding non-ASCII content, along with localized MCP custom prompts for 17 languages.

✨ What's New

🔄 Automatic Encoding Upgrade

PowerShell.MCP now intelligently manages file encodings by automatically upgrading from ASCII to UTF-8 when non-ASCII characters are added:

# Start with an ASCII file
"Hello World" | Set-Content test.txt -Encoding ASCII

# Add Japanese text - automatically upgrades to UTF-8
Add-LinesToFile test.txt -Content "こんにちは世界"
# ℹ Info: Content contains non-ASCII characters. Upgrading encoding to UTF-8.

Key Benefits:

• Prevents data loss when adding multi-byte characters to ASCII files
• Original ASCII files remain ASCII until non-ASCII content is added
• UTF-8 files remain UTF-8 (no unnecessary conversions)

🌐 Localized MCP Custom Prompts

MCP custom prompts are now localized for 17 languages (en-US, ja-JP, es-ES, fr-FR, de-DE, zh-CN, zh-TW, ko-KR, pt-BR, ru-RU, it-IT, nl-NL, pl-PL, tr-TR, ar-SA, hi-IN, sv-SE).

Example: "Software Development" → "ソフトウェア開発" (Japanese)

Note: Prompts are displayed in your operating system's display language.
