There are three major smart-font technologies in common use:
SIL Graphite is open source. It has been recently built in to several major applications such as Firefox and Thunderbird.
To learn more about complex fonts, a good place to start is in SIL's Non-Roman Script Initiative pages.
Font subsets for mobile technology
Please refer to Font Subsets - a new initiative at SIL.
- SIL's Non-Roman Script Initiative has created very comprehensive fonts for Latin and Cyrillic character sets. These are very large fonts that cover just about every need we know about in the Latin and Cyrillic world. Now, as we move into the age of mobile phone and web usage, everyone wants fonts that are small and compact. Our fonts are over a megabyte each and that is considered way too big for mobile phone usage.
- We are now considering ways to subset our fonts. Current commercial font subsetting schemes remove the smart font information from a font when it subsets a font. While this may be acceptable for majority languages, we consider this unacceptable as so many languages in the world require smart diacritic positioning above and/or below base characters. ...
These are some suggested fonts for use with SWORD tools. Any of these work with either Linux or Windows tools, and probably Macs as well, though certain fonts work better with different tools. They're TrueType or OpenType fonts, which means that usually just copying *.ttf to the right place makes them available, and that's necessary only if you don't have some sort of package manager or font installer to do it for you.
GNU FreeFont, consisting of serif, sans serif, and monospaced typefaces in regular, bold, italic, and bold italic fonts, is an attractive set of open source fonts covering a broad range of scripts in the first two Unicode planes. Many of the glyphs incorporated into FreeFont were designed by professional type foundries.
- A derivative of the above Free Serif typeface, FreeIdgSerif, was designed for Indo-Eurpoeanists, but has wide character coverage of use to Bible users.
GNU Unifont Glyphs from Unifoundry.com. This page contains the latest release of the GNU Unifont, with glyphs for every printable code point in the Unicode 5.1 Basic Multilingual Plane (BMP). It was the intention of the site owner to provide an update for Unicode 5.2 coverage, which added almost 1000 newly assigned code points.
Linux Libertine is a very pretty typeface that provides quality character sets for all of Latin, Hebrew, and Greek, which makes it especially useful for commentaries that use all three. While it is designed for Linux, it works quite well under Windows, as a display typeface for SWORD tools.
There is quite a selection of other fonts available from SIL. Visit SIL and look around, but the Charis SIL and Doulos SIL typefaces, in particular were designed with fairly broad coverage in mind.
Code2000 – now open source -- aims at complete coverage of the Unicode Basic Multilingual Plane (BMP) aka Plane 0. See also the freeware fonts Code2001 and Code2002, which are Plane 1 and Plane 2 fonts, respectively.
Quivira is a free Unicode font in the OpenType format which is supported by every usual office program or printer. Unicode font means it contains more than the standard characters for some western European languages. Quivira provides a large character repertoire, so that texts containing rather unusual characters can be rendered pleasingly.
Fonts for Scholars (Latin, Germanic Languages, Greek, Hebrew and Linguistics) – Materials compiled by David J. Perry Rye High School, Rye, New York. Download the Unicode font called Cardo from this site, released under the SIL Open Font License.
- ↑ Some Unicode fonts do not render a zero width space correctly. Code2000 displays some space to the left of the codepoint. cf. Tahoma displays them correctly (invisible). Bear this in mind when selecting the font directive for a Sword module in the conf file.
- ↑ Having tried this font in Xiphos 3.2.0 for Windows, I found that it required lines double spacing.
For particular requirements on languages not listed here, it is generally useful to visit the Wikipedia page for the relevant alphabet or script.
For Biblical languages, it is advisable to visit SBL Educational Resources.
"Gentium" is a good font for Greek. Look in repositories for gentium-fonts-1.02-5.fc7.noarch.rpm or go instead to  to get the *.zip.
"Ezra SIL" is SIL's best font for Hebrew and works very well in most SWORD front-ends. 
For BibleTime, the best Hebrew fonts are the Culmus fonts, particularly the Frank Ruehl CLM or Drugulin CLM. Many Linux distributions have a Culmus fonts package (Mandriva calls it fonts-type1-hebrew). If your distribution doesn't have this package, you may check out the Culmus Project site .
See also Hebrew Support for Your Browser at the Mechon Mamre website. For front-ends that use a browser (or browser engine) to display Bible text (e.g. FireBible), this may be relevant if you have a problem displaying Hebrew vowels and/or cantillation marks.
Another resource of free/libre and open source Hebrew fonts is The Open Siddur Project.
For Vietnamese, fonts like Arial and Linux Libertine work well. However, the UVN fonts are excellent options that are designed for Vietnamese and can be downloaded for free. They can be used for English or other languages that use a Latin alphabet. UVN Saigon looks particularly good with many SWORD front-ends. You can find these fonts at the TTi website .
Apart from MS Arial, which is mentioned above as a good all round font, the prettiest free font is probably Nazli, available from Farsiweb and part of many Linux repositories.
See also X Series 2 fonts – freely available fonts extended to support Persian, Arabic, Urdu, Pashto, Dari, Uzbek, Kurdish, Uighur, old Turkish (Ottoman) and modern Turkish (Roman).
In the same region, the Azeri module actually specifies the Nazli font. This can be downloaded from here.

New Athena Unicode is one of them. For further Coptic Unicode resources, see  and . See also  and . Coptic readers prefer glyphs to be like those of the New Athanasius Coptic Font as it's similar to many printed Coptic books, and so easier to read.
The TrueType font AmazighU_Arial is a Unicode font that supports the Kabyle alphabet. However, this is a copyrighted font, made by the Monotype Corporation.

It's listed here as an interim option for Bible translators needing to test their privately built modules on any platform in which this font can be installed.
- Special provision should be made when normalizing Tibetan characters in Unicode. See Encoding Model of the Tibetan Script in the UCS.
Detailed recommendations are given by the Government of Nunavut in its Inuktitut fonts and tools page.
With only 0.01 people per square kilometer of land, Nunavut is one of the least populated regions in the world. And yet it has four official languages: English, French, Inuktitut and Inuinnaqtun. For this reason, the government of Nunavut adopted a clean sans-serif font called Pigiarniq (designed by Tiro Typeworks) that enables its people to use all four languages in a uniform manner. The result is a professional-looking free font family.

Although the default Unicode font for most front-ends may display Armenian normal text, finding a freely distributable open font that displays text in italics is proving more of a challenge. In Windows, the Sylfaen font does a reasonable job, even with italics, though this is not one that we can redistribute. For background, see Armenian alphabet.
