2135

2135 is the Unicode hexidecimal number for the Gregory-Aland Codex Sinaiticus siglum (ℵ). This siglum is distinct from the Hebrew character Aleph which means that when you include this character, the text direction does not change. Although many are not friendly to Microsoft Word, the various critical sigla from the Nestle-Aland editions all have unicode designations. For an overview, read this old blog entry at Four Senses. The Unicode Consortium has a PDF with most of the relevant encodings, here.
