SIL Open Font License（简称OFL）是一种开源字体许可协议，由SIL International制定，旨在促进字体的自由共享、使用和修改。OFL版本1.1是最常用的版本，它允许用户自由地使用、复制、修改、合并、出版、分发、再许可和/或销售字体软件的副本，同时也允许将字体软件作为一部分包含在其他软件中，但必须遵循一定的条件。

SIL Open Font License 1.1

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.

The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

DEFINITIONS
“Font Software” refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.

“Reserved Font Name” refers to any names specified as such after the copyright statement(s).

“Original Version” refers to the collection of Font Software components as distributed by the Copyright Holder(s).

“Modified Version” refers to any derivative made by adding to, deleting, or substituting – in part or in whole – any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.

“Author” refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.

PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining a copy of the Font Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and unmodified copies of the Font Software, subject to the following conditions:

1. Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself.

2. Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold with any software, provided that each copy contains the above copyright notice and this license. These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user.

3. No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.

4. The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission.

5. The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.

TERMINATION
This license becomes null and void if any of the above conditions are not met.

DISCLAIMER
THE FONT SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM OTHER DEALINGS IN THE FONT SOFTWARE.

序言
开放字体许可证（OFL）的目标是刺激全球合作字体项目的发展，支持学术界和语言界的字体创建工作，并提供一个自由开放的框架，在这个框架中，可以与其他人合作共享和改进字体。

OFL允许许可字体自由使用、研究、修改和重新分发，只要它们不是自己出售的。字体，包括任何衍生作品，可以与任何软件捆绑、嵌入、重新分发和/或出售，前提是衍生作品不使用任何保留名称。然而，这些字体和衍生产品不能在任何其他类型的许可证下发布。字体保留在此许可证下的要求不适用于使用字体或其衍生物创建的任何文档。

定义
“字体软件”是指版权持有人根据本许可证发布并明确标记的一组文件。这可能包括源文件、构建脚本和文档。

“保留字体名称”是指在版权声明之后指定的任何名称。

“原始版本”是指由版权持有人分发的字体软件组件的集合。

“修改版本”是指通过添加、删除或替换（部分或全部）原始版本的任何组件、通过更改格式或通过将字体软件移植到新环境而产生的任何衍生产品。

“作者”是指为字体软件做出贡献的任何设计师、工程师、程序员、技术作家或其他人。

权限和条件
特此免费授予任何获得字体软件副本的人使用、研究、复制、合并、嵌入、修改、重新分发和销售字体软件的修改和未修改副本的权限，但须符合以下条件：

1. 字体软件及其任何单独组件，无论是原始版本还是修改版本，均不得自行出售。

2. 字体软件的原始或修改版本可以与任何软件捆绑、重新分发和/或出售，前提是每个副本都包含上述版权声明和本许可证。这些可以作为独立的文本文件、人类可读的标题或文本或二进制文件中适当的机器可读元数据字段包括在内，只要用户可以容易地查看这些字段。

3. 除非获得相应版权持有人的明确书面许可，否则字体软件的任何修改版本都不得使用保留字体名称。此限制仅适用于呈现给用户的主字体名称。

4. 字体软件的版权持有人或作者的姓名不得用于推广、背书或宣传任何修改版本，除非是为了承认版权持有人和作者的贡献或获得其明确的书面许可。

5. 字体软件，无论修改或未修改，部分或全部，都必须完全根据本许可证进行分发，不得根据任何其他许可证进行分销。字体保留在此许可证下的要求不适用于使用字体软件创建的任何文档。

终止
如果不满足上述任何条件，本许可证将无效。

免责声明
字体软件是“按原样”提供的，没有任何明示或暗示的保证，包括但不限于对适销性、特定用途的适用性以及不侵犯版权、专利、商标或其他权利的任何保证。在任何情况下，版权持有人均不承担因使用或无法使用字体软件或字体软件的其他交易而产生的任何索赔、损害或其他责任，包括任何一般、特殊、间接、附带或后果性损害，无论是在合同诉讼、侵权行为还是其他方面。
