+# postcss-normalize-charset
+
+Add necessary or remove extra charset with PostCSS
+
+```css
+a{
+  content: "©";
+}
+```
+
+```css
+@charset "utf-8";
+a{
+  content: "©";
+}
+```
+
+## API
+
+### normalizeCharset([options])
+
+#### options
+
+##### add
+
+Type: `boolean`  
+Default: `true`
+
+Pass `false` to stop the module from adding a `@charset` declaration if it was
+missing from the file (and the file contained non-ascii characters).
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
+
+## Contributors
