Other complex scripts may apply shaping operations over entire words or over the entire text run, with no subdivision required. </p> <p> Non-complex scripts, by definition, do not require these operations. However, correctly shaping a text run in a non-complex script may still involve Unicode normalization, ligature substitutions, mark positioning, kerning, and applying other font features. The key difference is that a text run in a non-complex script can be processed sequentially and in the same order as the input sequence of Unicode codepoints, without requiring an analysis stage. </p> </div> <div class="footer"> <hr>Generated by GTK-Doc V1.32</div> </body> </html>
