The current font used on site (Georgia) renders Hebrew letters smaller than their English counterparts. In posts, this causes no problems, as 15px is plenty large enough to read clearly. However in comments and in sidebars (13 and 12 px, respectively) it becomes hard to discern nekudos (vowels) and even between certain similar letters (ר - ד , כ - ב).
Is changing just the font size of the Hebrew letters while leaving the English the same possible/practical? If not, is there a similar font that has slightly larger Hebrew letters?
