In the tutorial on setting the Page Settings, it is advised to leave the exact ISO that is given as default untouched unless you really need to do otherwise.

Maybe I misinterpretate this, but this has to do with other alphabets I assume?

In case I wish to add a few lines (amongst the regular English content) or entire page in Hebrew (since I do have several friends in Israel for whom I may want to add a small translation of some pages or paragraphs), do I need to make any changes to the page settings or can one just type the Hebrew content without any settings needed to be changed? I must add I am unsure which the code for Hebrew alphabet would be.
