Use literal search for find in range (/ and ?)

Personally I find it pretty cumbersome to escape regex sequences when using Vintageous search functionality (/ and ?). For example, if I want to quickly jump to the next occurence of { (including other lines) I have to enter \{.

From what I can tell, vim searches literally by default. It would be nice to have a setting to enable regex search, but literal search should be the default in my opinion.
