Title: Avoid infinite loop when DELIMITERS data is wrong

When and entry in the `DELIMITERS` array has an `HW` entry that indicates a character in a font that doesn't actually include that character, MathJax would loop infinitely trying to find make a stretchy delimiter for that character. This patch avoids the loop and defaults to a generic unicode character instead.
