This seems to already be handled by the else clause that you added. By having it here this code is executing twice and some of the text is not covered by the earlier quote and brace checks.
Suggested change
| index += ConvertTextAtIndexToRune(tokenText, index, result, offset); |

Not entirely sure I follow. If we move the characters by a certain amount the index will always need to be added to. CreateNextInString will consume some number of characters to produce a virtualChar. That's separate from ConvertTextAtIndexToRune
