-# Markdown-it Wordless
-
-A [markdown-it](https://markdown-it.github.io) plugin
-to optimize wordless multi-language line-break render.
-
-When a paragraph is long in markdown, we usually separate them into lines,
-and it will finally be rendered into a single line inside HTML.
-But for wordless languages (such as Chinese and Japanese),
-they do not use spaces to separate words,
-that they don't need a space to be added when processing line-break.
-
-If you are only working with a single wordless language,
-you can definitely use the following code,
-which will disable all spaces when line break
-(render single `\n` into an empty string rather than a space):
-
-```ts
-import md from "markdown-it"
-md.renderer.rules.softbreak = () => ""
-```
-
-But once working with multi-languages,
-especially when there's a mix of wordless and wordful languages,
-such as using Chinese and English in a single markdown document,
-such options cannot handle all cases.
-So here comes this `"markdown-it-wordless"` plugin,
-and you can use it like this:
-
-```ts
-import md from "markdown-it"
-import {Options} from "markdown-it-wordless"
-md.use(wordless)
-```
-
-## Basic rules
-
-1. Wordful languages (such as English and Arabic) will be rendered as usual.
-2. It won't add a space when line break between the same wordless language.
-3. It will add a space when line break between different wordless languages.
-4. Specially, Chinese and Japanese will be treated as a same language,
-   as there are many shared characters between them,
-   and their character styles are almost the same.
-5. Although Korean characters are like Chinese and Japanese (CJK),
-   Korean is not a wordless language, it uses spaces to separate words.
-
-## Use it with VitePress
-
-[VitePress](https://vitepress.dev) is an excellent static site generator,
-and this package is also inspired when the author using VitePress.
-It's strongly recommended to add such plugin to VitePress
-if you are using wordless languages. And here's how to config:
-
-```ts
-// <root>/.vitepress/config.ts
-import {defineConfig} from "vitepress"
-import {wordless} from "markdown-it-wordless"
-
-export default defineConfig({
-  markdown: {
-    config(md) {
-      md.use(wordless)
-    },
-  },
-  // Other configs...
-})
-```
-
-## Customize to optimize performance
-
-The default option will enable optimization
-for all registered wordless languages inside this package.
-If you want to optimize performance,
-you can specify what exactly wordless language you are using.
-You may also specify what wordful language you are using,
-because there's only optimization for wordful languages
-which unicode is less than `0x0dff`.
-
-Here's a simple example
-if you will only use Chinese or Japanese as wordless languages:
-
-```ts
-import md from "markdown-it"
-import {wordless, chineseAndJapanese, Options} from "markdown-it-wordless"
-md.use<Options>(wordless, {supportWordless: [chineseAndJapanese]})
-```
-
-Such optimization is unnecessary in most cases,
-because this plugin will not slow down the rendering process a lot
-in common cases (only a few milliseconds).
-And if you do want to customize,
-please make sure you've understand the source code. Please refer to
-[`data.ts`](https://github.com/treeinfra/markdown-it-wordless/blob/main/data.ts)
-for more details,
-and here's documentation for each item in details.
-
-## About the supported languages
-
-You can find all supported languages
-in the source code of
-[`data.ts`](https://github.com/treeinfra/markdown-it-wordless/blob/main/data.ts).
-Each language or language series is an exported const
-that you can import and call.
-
-The languages series are based on the [Unicode](https://unicode.org/charts/).
-Most of the languages are coded manually and some of them are
-generated by several AI models. So that there might be mistakes,
-and the author cannot guarantee the accuracy of the data
-because it's almost impossible for a single person to learn all such languages.
-
-If you are native speaker of one of the those wordless languages
-and you find there are some mistakes,
-or if there's even some wordless languages not included in this package,
-please feel free to open an issue.
