Currently Wifi SSID with UTF8 that is not in the ASCII character set will not output correctly.

Motivation and Context

How Has This Been Tested?

Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• System.Device.Wifi/WifiAdapter.cs is excluded by none and included by none

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Pull Request Overview

This PR fixes an issue with WiFi SSID encoding where SSIDs containing UTF-8 characters outside the ASCII character set were not displayed correctly. The fix changes from character-by-character conversion to proper UTF-8 decoding.

• Replace manual character conversion loop with UTF-8 encoding
• Add System.Text namespace import for UTF-8 functionality
• Use byte array instead of char array for raw SSID data
