Easy-to-use Unicode Table for Hebrew Characters (Alef-bet)
This chart shows Unicode Hexadecimal values for
Hebrew characters. To display the Hebrew characters you need an
appropriate font. I use the Ezra SIL font
which shows almost all of the characters.
Other Hebrew fonts that support not only the Hebrew characters but the punctuation, vowel and cantillation marks
are discussed on Mechon Mamre's font page.
