File doesn't appear in "Find in Files" result if it contains ASCII control character 1C
If a file contains ASCII character 1C ("File separator"), then it never appears in "Find in Files" results.
Searches within the document seem fine, it's just for "Find in files" that it doesn't appear.
To reproduce, create a file containing some known text, plus a 1C character. Then find in files for that known text. The file does not appear in the results.
