Example URL:
https://www.bookreviews.org/bookdetail.asp?TitleId=12210

Steps to reproduce the problem:
1. Use Chrome settings to add all Italian languages.
2. Navigate to URL provided and note book title in bold lettering at top of this web page. (Title is in Italian.)
3. Hit reload button repeatedly and watch book title. Typically after about three or four reloads, the  special characters in the book title will change from "ò" (correct) to "ň" (incorrect) and from "è"(correct) to "č" (incorrect) or vice versa.
4. Continue to reload the page, and you'll see this pattern continue (i.e., special characters change from incorrect to correct characters or vice versa).

Correct foreign characters should render correctly in the browser at all times.
