Apparatus SIL

Symbols used for Biblical text apparatus

NRSI team, 2009-06-12


You may be interested to know that all of the characters in Apparatus SIL are now supported in Charis SIL, Doulos SIL, Gentium Plus and Andika. The specific "apparatus" glyphs are the same in each font; the design of the apparatus characters was not updated to match the design of each font.


The Apparatus SIL fonts are the Unicode version of their predecessor, SIL Apparatus. The design is the same, only the encoding is different. The Apparatus SIL fonts were designed to provide most of the symbols needed to reproduce the textual apparatus found in major editions of Greek & Hebrew biblical texts. The fonts include:

The basic ASCII character set plus some international characters

Superscript characters

Certain Greek, Hebrew, Gothic (Fraktur) and other letters used for manuscripts

Special punctuation

Other Signa and Sigla used in documenting manuscript contents

These fonts were based on SIL Charis, a font designed for optimum clarity and compactness when printed at small point sizes. This assures that both Charis SIL and Apparatus SIL can be used together in documents with a consistency of style.

Most lines of text in the apparatus can be reproduced by combining the Greek and Hebrew fonts, transliteration (using a font such as Charis SIL), and the Apparatus SIL font.


These fonts utilize OpenType and Graphite technology to provide rendering information needed by application and system software. Usability of the features provided in these fonts will depend on the exact capabilities of your software. Some of the characters are in plane 1 of Unicode and your software will need to be able to display plane 1 characters.

Supported character ranges


The original SIL Apparatus font contained some superscript characters that are not in Unicode. Those characters are superscript (or modifier) lambda mu pi rho ? C F Q S X Y Z q / [ ] . , – *. Rather than encode them in SIL’s Private Use Area (PUA), we have chosen not to include those characters in this Unicode font.
