FONTLOG Charis SIL font family ======================== This file provides detailed information on the Charis SIL family of fonts. This information should be distributed along with the Charis SIL fonts and any derivative works. Basic Font Information ---------------------- Charis is similar to Bitstream Charter, one of the first fonts designed specifically for laser printers. It is highly readable and holds up well in less-than-ideal reproduction environments. It also has a full set of styles - regular, italic, bold, bold italic - and so is more useful in general publishing than Doulos SIL. Charis is a serif proportionally spaced font optimized for readability in long printed documents. The goal for this product was to provide a single Unicode-based font family that would contain a comprehensive inventory of glyphs needed for almost any Roman- or Cyrillic-based writing system, whether used for phonetic or orthographic needs. In addition, there is provision for other characters and symbols useful to linguists. This font makes use of state-of-the-art font technologies to support complex typographic issues, such as the need to position arbitrary combinations of base glyphs and diacritics optimally. Four fonts from this typeface family are included in this release: * Charis SIL Regular * Charis SIL Bold * Charis SIL Italic * Charis SIL Bold Italic The design of the basic character set of Charis SIL is similar (but not identical) to Bitstream Charter, designed by Matthew Carter. The following notice accompanied the Charter fonts: (c) Copyright 1989-1992, Bitstream Inc., Cambridge, MA. You are hereby granted permission under all Bitstream propriety rights to use, copy, modify, sublicense, sell, and redistribute the 4 Bitstream Charter (r) Type 1 outline fonts and the 4 Courier Type 1 outline fonts for any purpose and without restriction; provided, that this notice is left intact on all copies of such fonts and that Bitstream's trademark is acknowledged as shown below on all unmodified copies of the 4 Charter Type 1 fonts. BITSTREAM CHARTER is a registered trademark of Bitstream Inc. SIL International is the creator of the Charis SIL fonts, and is the owner of all proprietary rights therein. A Note Regarding the Open Font License and TypeTuner ---------------------------------------------------- The OFL prohibits the use of Reserved Font Names "Charis" and "SIL" in the name of any font that is derived from the Original Version of Charis SIL. However, SIL International (the Copyright Holder) grants through this separate written agreement the right to use the Reserved Font Names in any Modified Version of this font created by using TypeTuner as long as the feature information contained in the Original Version is used, unmodified, as the source for TypeTuner feature information, and "Charis SIL" is not the resulting font family name. TypeTuner-produced fonts created in this manner are still bound by the terms of the OFL. Specifically, the use of Reserved Font Names is prohibited when making derivatives of a TypeTuner-produced font. Anyone making a derivative of a TypeTuner font will need to find a different name. For example a TypeTuner-produced font may be named "Charis SIL Literacy SomeFarAwayPlace" but a derivative of that font made with other tools would not be allowed to use the "Charis" and "SIL" Reserved Font Names and would have to be named something like "Grace Foo".

For information on what you're allowed to change or modify, consult the OFL and OFL-FAQ. Anyone can make their own modified version of Charis SIL (using a different name), but SIL International will continue to maintain and develop the canonical version of the Charis SIL fonts. As the package maintainer, we welcome contributions. Here are some things to keep in mind: Format: We are open to contributions in various formats, but if you want to maximise the chances of us including your work, please make it available to us (via email or a URL) as either a FontLab database (preferred) or a PostScript Type 1 (or OT-CFF) font. Source files: We are not yet making the extended source files available, because our build system is rather complex and difficult to reproduce. We hope to include an easier process in the future. Copyright attribution: If you submit something for inclusion in the main Charis SIL fonts, we will ask you to affirm that it is your original work, and ask you to assign the copyright of your work to SIL International. This is to ensure that future releases can be made under improved versions of the OFL without needing to track you down for further permission. This follows the same principle used by the FSF. Keep in mind that we are a not-for-profit organization committed to free/libre and open source software, and that any contributions incorporated in the fonts will always be available under the OFL or a similar license. Quality: Because we want to be able to guarantee a high level of quality for the primary Charis SIL fonts, we will review submissions carefully. Please don't be discouraged if we do not include a submission for this reason, or ask you to make specific revisions. Types of contributions: If you wish to make a contribution - a set of additional glyphs, scripts, code, etc. - please contact us before you do any work to see if it is a contribution we currently need. Every addition adds to the complexity of the project and needs to be carefully planned. This also avoids two people working on the same type of addition at the same time. Linux packages: Please contact the upstream maintainer of the various packages - nicolas_spalinger@sil.org - if you want to help package or maintain a package. When submissions will be included: We plan to revise the fonts when major updates are needed (eg new versions of Unicode). If you wish to make submissions, contact us on the timing.
