When you have words in Latin and Hebrew letters mixed on the same page, the sequences of words are normally written properly due to the inherent directionality of characters. Hebrew passages run right to left.
But when characters like parentheses are involved, things get more complicated. Parentheses are directionally neutral (or utral) and participate in the direction of adjacent characters. Problems arise when they appear between Latin and Hebrew letters. A simple remedy is to use the LEFT-TO-RIGHT MARK character, representable in HTML as ‎
, for example
here are some words <span class='h'>הנה כמה מילות</span> ‎(100, 200)
