Fonts & Character Sets ⇒ Switching between languages?

[jbutzu]

Hi there. I am writing a book where I need to be able to make several references to a Hebrew Text and therefore need to write in Hebrew (with vowel points). I have the fonts I would like to use already installed on my computer. Would someone please be kind enough as to walk me through the correct process so as to be able to easily switch back and forth between English and Hebrew. I do not want to use Unicode as I cannot (to my knowledge) insert all the characters that are necessary (mainly the vowel points).

Thanks in advance.
John
