From time to time, or often depending on your field of work, you might have to type textual criticism signs in you paper, thesis, masterpiece, and what not. Oftentimes the problem is finding the signs and then entering them into your document. There are several ways to find them: websites, the Character or the Glyph Palette of your system and sofware, etc. There also several ways to enter them, some more practical than others.
This is what the font looks like (picture from the SBL site).
The font contains 1341 signs, all you need to reproduce the text of the Greek New Testament or the Septuagint and the majority of the signs necessary for NT textual criticism. As this picture shows (displayed are default font, rare ligatures, variant 4, and variant 6, and samples of nomina sacra), the font offers variants of the thêta, rhô, the sigma as well as all you need to write nomina sacra.
Depending on the operating system and the sofware you use, entering right-to-left scripts can be a real problem. On the Mac it seems Word is not going to offer satisfying RtL anytime soon. Mellel is quite good with Hebrew but is weak or non-existent in tables, images, parallel columns, indexes, etc.
One of the advantages LaTeX offers is the possibility to work with ancient languages without too much trouble. Here are the basic instructions to use Biblical Hebrew in XƎTeX (this works fine on a Mac with Leopard).
To write in Greek in XƎTeX is actually quite simple, especially if you use a font that contains all the characters needed to write in English (or whichever languages you use) and in Greek (like Gentium, Cardo, etc.). To type in Greek. The following instructions are specific for the Mac. If you use XƎTeX on Windows or LinuxLes you just need to adapt the commands for choosing fonts to your environment. These instructions also apply to working with Greek from other periods or other ancient or other non latin languages, provided you use the appropriate font.
