Steps to Reproduce:

1. Create a text file in GB2312 and UTF-8 formats.
2. Begin query
3. It can be observed that the search results vary depending on the value of the files.encoding configuration. However, both of these encodings are Simplified Chinese, and I need them to be searchable in both cases.

**In a scenario like this, opening a UTF-8 formatted file allows searching in both formats.**
