How to keen the “r” characters in a string without any carrige return [closed]

I have an array where each element represents some text in a given language.
One of the languages is Coptic. Some of the text incudes the “r” characters as part of the language charcters (which the CSS font interprets into some Coptic letter when the text is rendred in an html element):

example:

"`mmoc nN`èrhi de 'en pi`èabot `èmma"

The “r” in “èrhi” represents some Coptic character not a carrige return.

I tried replacing r by \r in my string. I also tried to replace it by \r. It didn’t work.

How to force javascript to deal with “r” as normal string and ignore the escape characther before the letter “r”?
