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.

Smart font routines automatically +adjust the position of diacritics to support and optimize arbitrary +base+diacritic combinations. + +Charis SIL is optimized for readability in long printed documents. It is +highly readable and holds up well in less-than-ideal reproduction environments +due to its simple and robust design with strong serifs and clear features. + +## Note regarding Charter + +This Charis SIL font is essentially the same design as the SIL Charis font +first released by SIL in 1997.

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. - -Acknowledgements ----------------- (Here is where contributors can be acknowledged.
