_curses.error: chgat() returned ERR when searching for a specific string #109

Hi,

In a certain ebook, when I search for the word "abuse" it causes epy to crash. Searching for other strings does not cause it to crash.

Traceback (most recent call last):

pipx upgrade epy-reader 
epy-reader is already at latest version 2023.6.11 (location: /home/jason/.local/pipx/venvs/epy-reader)

I also tested on a different epub and I did not get the same crash.

I can supply the epub for testing purposes if need be.
