Unicode Hebrew Code Block (PDF)
Unicode Alphabetic Presentation Forms (PDF), including forms used in standard Yiddish orthography. Note 1: these forms are generally to be used for compatibility; modern applications should use composition of characters from the Hebrew code block. Note 2: this now includes U+FB1D, Hebrew Letter Yod with Hiriq, which was added as part of Unicode 3.0, and which represents a character combination used in Yiddish. Note 3: there now exists an important Corrigendum #2: Yod with Hiriq Normalization, effective for Unicode 3.1, basically to deal the character U+FB1D HEBREW LETTER YOD WITH HIRIQ being mistakenly omitted from the so-called "Composition Exclusions table", i.e., such that it was not handled the same as all the other precomposed Hebrew characters.

Unicode 4.0 / ISO 10646 Plane 0, by Frank da Cruz, is useful. It's a web page displaying every basic Unicode character and its code and name. (There's also a link there for some useful code for creating this web page.)
