How to Type ÿ (Y with umlaut) on LaTeX

Published July 24, 2026, 2 min read

Typing ÿ (y with umlaut) on LaTeX takes a few seconds once you know the trick. The short answer is \"{y}. Read on for step-by-step instructions, the uppercase Ÿ and what to do when a method does not work.

ÿ on LaTeX: \"{y}

Ÿ on LaTeX: \"{Y}

Or copy it:

Method 1: LaTeX command

Write \"{y} in text mode. Load \usepackage[T1]{fontenc} for correct hyphenation and copy-paste from the PDF.

Method 2: Type the character directly

Since 2018 pdfLaTeX reads UTF-8 by default, so you can paste ÿ into your source. On Overleaf, set the compiler in Menu → Compiler.

Method 3: In math mode

For a variable with this accent, use $\ddot{y}$ . Math accents are for symbols, so use the text command for words.

How to type the capital Ÿ

The uppercase form works the same way with Shift added where a letter is typed.

About the letter ÿ

ÿ is Unicode U+00FF, named LATIN SMALL LETTER Y WITH DIAERESIS. It is used in French. Two dots above a letter. As a German umlaut it changes the vowel sound (ä, ö, ü); as a diaeresis in French, Dutch, Spanish or English (naïve, Noël) it shows that a vowel is pronounced separately. See the ÿ character page for every code and shortcut.

Troubleshooting

Accents on i and j need the dotless forms \i and \j in old LaTeX; modern LaTeX handles this automatically.
If the letter is missing in the PDF, the font lacks it. Switch to XeLaTeX or LuaLaTeX with a broader font.
Wrap commands in braces when the next character is a letter: \'{e}x, not \'ex.
