We welcome other developers who wish to get involved in supporting and enhancing this software.

Permissions Granted by the OFL

SIL’s Arabic script fonts are licensed according to the terms of the SIL Open Font License. For specific information on permissions granted by the OFL, such as freedom to make your own versions or the freedom to bundle, see the OFL FAQ.

Developer notes

Each of our Arabic script projects use a UFO-based design and production workflow, with all sources in open formats and a completely open-source build toolkit. For more details see SIL Font Development Notes.

We welcome contributions to these font projects, such as new glyphs, enhanced smart font code, or bug fixes. The best way to begin the process is to file an issue in the Github project (Alkalami, Awami Nastaliq, Harmattan, Lateef, or Scheherazade New) or respond to an existing issue and express your interest. Then we can begin to correspond with you regarding what all might be required and discuss how to best submit your contributions.

To enable us to accept contributions in a way that honors your contribution and respects your copyright while preserving long-term flexibility for open source licensing, you would also need to agree to the SIL International Contributor License Agreement for Font Software (v1.0) prior to sending us your contribution. To read more about this requirement and find out how to submit the required form, please visit the CLA information page.

Copyright attribution

If you submit something for inclusion in the main 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 Free Software Foundation (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.


Because we want to be able to guarantee a high level of quality for our 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.
