How do I place a single character from unicode in a LaTeX document?

Question

I want to place a character from several, non-Latin, languages. I guess I can do this using unicode, but how do I do that? Specificaly, I want to place the Hebrew Aleph and the digit currently used in Arabic for 1.

Answer 1

First, you need to make sure you use a font which supports these characters.

Then, you could simply type the character or copy it from somewhere.

Otherwise, using XeTeX or LuaTeX, if you know the code, you can use \char"<thecode>, for example:

\char"2135 will typeset an Hebrew aleph (ℵ), and \char"0661 for an Arabic one (١).
