Double-quotes in fulltext search string causing server errors

[setagana]

Version affected: 1.4.2

I'm having an issue with my prismic site built in .NET. I'm making use of the fulltext search api and whenever a search string containing a double quote is entered, it results in a server error which begins with

prismic.Error: {"message":"]' expected but [' found

Do I need to do any trimming of characters in the search string prior to passing them to your API and, if so, do you have a full list of dangerous characters that need to be stripped?
