Unable to Search for Japanese Characters in Xcode 15 RC Editor Using Command+F

I am experiencing an issue with the search functionality in Xcode 15 RC's editor. Specifically, I am unable to search for Japanese characters (Kanji, Hiragana, and Katakana) using the Command+F search bar.

Steps to Reproduce:

1. Open any project in Xcode 15 RC.
2. Open a file that contains Japanese characters.
3. Press Command+F to bring up the search bar.
4. Attempt to input Japanese characters into the search field.

Example:

• Problematic Input and Output:
  • nyuuryoku → にゅうryおkう
• Expected Input and Output:
  • nyuuryoku → にゅうりょく

Expected Behavior:

The search bar should allow for the input of Japanese characters, and the search should return appropriate results.

Actual Behavior:

I am unable to input Japanese characters correctly into the search bar, making it impossible to search for lines of code or comments written in Japanese.

System Information:

• macOS version: [Your macOS version]
• Xcode version: 15.0
• Keyboard input source: Japanese

I hope this issue will be addressed soon, as it significantly hampers the workflow for developers who work with Japanese text.
