Basic Search not working with UTF-16LE encoded file

Summary

When I try to search my project the search function does not seem to query the files in my project.

Steps to reproduce

1. Open "Test" project
2. Search for anything (ex. "Create")
3. This will provide no results even though the word "Create" is in dbo.luAcademicYear.table

Example Project

https://gitlab.com/tankusb/test

What is the current bug behavior?

Search results will not yield anything

What is the expected correct behavior?

When I search the word "create" the location of this word will show up
