           <p>The compatibility normalization forms (form NFKC and form NFKD) change the structure and lose the meaning of the text in important ways. Users sometimes use characters with a compatibility mapping in Unicode on purpose or they use characters in a legacy character encoding that have a compatibility mapping when converted to Unicode. This has to be considered intentional on the part of the content author. Although NFKC/NFKD can sometimes be useful in "find" operations or string searching natural language content, erasing compatibility differences is harmful.</p>
