字体的授权陷阱

Font licensing traps

**这一步决定什么****What this stage decides**：每个人都会检查图片和音频的授权，很少有人检查字体 —— 而绝大多数免费字体不含商用授权。: Everyone checks the licence on images and audio; almost nobody checks fonts — and most free fonts do not cover commercial use.

**本站的判断****Our judgement**：用字体前，截图看它的授权页，搜「商用」两个字。搜不到就别用。: Before using a font, screenshot its licence page and search for the word \"commercial\". If it is not there, do not use it.

性质：本站的判断，未经实测Nature: the site's judgement, not measured

一句话：图片、音频、音效你都会查授权。字体是唯一被系统性忽略的一项。

In one line: you check the licence on images, audio and sound effects. Fonts are the only category that gets systematically ignored.

⚠ 为什么它特别危险

特征	图片/音频	字体
一眼能否看出是 AI 生成/抓来的	✅ 通常能	⚠ 看不出来 —— 它就是个字体文件
授权是否明确写在素材里	✅	⚠ 常藏在官网的「条款」页深处
⚠ 侵权后果	可能被要求下架	⚠ 可能被要求停止分发全部产品

⚠ Why it is especially dangerous

Property	Images / audio	Fonts
Can you tell at a glance that it was AI-generated or taken?	Usually	⚠ No — it is just a font file
Is the licence stated inside the asset?	Yes	⚠ Often buried deep on the provider's terms page
⚠ Consequence of infringement	Possibly a takedown	⚠ Possibly an order to stop distributing every product

⚠「个人免费」是陷阱

字体站最常见的授权写法是：

```

✅ 个人使用免费

✅ 商业使用需购买授权

⚠ 但常常没说清楚：

「个人」包不包括个人网站？
App 内嵌算商业吗？
⚠ 游戏内嵌呢？

```

⚠ 同一个字体在不同使用场景下，授权可能完全不同。

⚠ "Free for personal use" is a trap

The most common wording on a font site is:

```

✅ Free for personal use

✅ Commercial use requires a paid licence

⚠ But it rarely clarifies:

Does "personal" include a personal website?
Does embedding it in an app count as commercial?
⚠ What about embedding it in a game?

```

⚠ The same font can be licensed completely differently depending on the use case.

三个安全的做法

1. 选明确写着「开源授权」的字体

⚠ 注意区分「开源字体」与「免费字体」—— 前者授权清晰（OFL/Apache 等），

后者只是「不收你钱」。

2. 程序化生成字体

⚠ 用代码画字形（比如用矢量路径生成像素字体）—— 版权归你，没有授权问题。

⚠ 缺点是不好看，但至少不会出事。

3. 用引擎内置字体

⚠ Godot / Unity 等自带默认字体，授权随引擎（通常是引擎许可覆盖）。

⚠ 但要注意：引擎许可是否覆盖字体，要看引擎的官方说明 —— 别默认。

Three safe approaches

1. Pick fonts whose licence is explicitly open source

⚠ Distinguish an open-source font from a free font — the former has a clear licence (OFL, Apache, …), the latter merely charges you nothing.

2. Generate the glyphs programmatically

⚠ Drawing letterforms with code (for example generating a pixel font from vector paths) makes the copyright yours. ⚠ It looks worse, but it cannot get you into trouble.

3. Use the engine's built-in font

⚠ Godot, Unity and others ship a default font whose licence follows the engine's. ⚠ Check the engine's official statement that the licence covers the font — do not assume it.

实操

在资产台账里给字体单列一行：

文件	来源	授权
`ui.ttf`	某某字体站	⚠ 个人免费 —— 未确认商用

⚠ 「未确认商用」在发布前必须清零。见 [AI 资产台账](ai-资产台账.html)。

In practice

Give fonts their own row in the asset ledger:

File	Source	Licence
`ui.ttf`	some font site	⚠ free for personal use — commercial use unconfirmed

⚠ "Commercial use unconfirmed" must be cleared before shipping. See the [AI asset ledger](ai-资产台账.html).
