How the Upper Case Converter works

The converter uses your browser's Unicode-aware uppercasing, which handles accented and non-Latin letters as well as A to Z: café becomes CAFÉ, and the German ß becomes SS. Numbers, punctuation, spacing and line breaks are unchanged.

All caps works for short labels, headings and constants, but long passages in capitals are harder to read and can come across as shouting.
