+### Layout issues caused by stega encoding
+
+**Problem**: The invisible zero-width characters can cause unexpected letter-spacing or text breaking out of containers.
+
+**Solutions**:
+1. Use the `stripStega` prop to remove stega encoding after processing:
+   ```jsx
+   <ContentLink stripStega={true} />
+   ```
+
+2. Or use CSS to fix the letter-spacing issue:
+   ```css
+   [data-datocms-contains-stega] {
+     letter-spacing: 0 !important;
+   }
+   ```
+   This attribute is automatically added to elements with stega-encoded content when `stripStega` is `false` (the default).
