Quotation marks highlighted yellow in code editor

Hi, All of a sudden, quotation marks and apostrophes (i.e, ", ', and `) are interactively highlighted in yellow as I type them in the RStudio code editor. Please see screenshot below. I've looked through Options>Code to see if I accidentally changed this in preferences. Does anyone know why this might be? I'd like to turn it of if possible

I'm on a Mac with the latest version of RStudio.

I realized it was because I had accidentally changed my keyboard input source to U.S. - International. Issue solved by changing back to U.S.
