+# isWellFormedString
+
+> Test if a string is well-formed.

+<section class="usage">
+
+## Usage
+
+```javascript
+var isWellFormedString = require( '@stdlib/assert/is-well-formed-string' );
+```
+
+#### isWellFormedString( str )
+
+Tests if a `string` is well-formed.
+
+<!-- eslint-disable no-new-wrappers -->
+
+```javascript
+var bool = isWellFormedString( '' );
+// returns true
+
+bool = isWellFormedString( new String( '' ) );
+// returns true
+
+bool = isWellFormedString( '\uDBFF' );
+// returns false

+bool = isWellFormedString( '-5' );
+// returns true
+
+bool = isWellFormedString( null );
+// returns false
+```
+
+#### isWellFormedString.isPrimitive( str )
+
+Tests if a `string` is a well-formed `string` primitive.
+
+<!-- eslint-disable no-new-wrappers -->
+
+```javascript
+var bool = isWellFormedString.isPrimitive( '' );
+// returns true
+
+bool = isWellFormedString.isPrimitive( new String( '' ) );
+// returns false
+```
+
+#### isWellFormedString.isObject( str )
+
+Tests if a `string` is a well-formed `String` object.
+
+<!-- eslint-disable no-new-wrappers -->
+
+```javascript
+var bool = isWellFormedString.isObject( '' );
