Non-ascii characters not displayed correctly in Find in files

[jitseniesen]

Description

What steps will reproduce the problem?

1. Write a line containing a non-ascii character in a file, e.g. str = 'Viva España'
2. Use 'Find in files' to find that line, e.g. search for Viva

What is the expected output? What do you see instead?

I would have expected the non-ascii character to be displayed correctly in the "Find in files" pane. Instead I see a hex representation.

The below screenshot hopefully makes it clear. I would have liked to see España in the location marked with the red circle.
