About the letter ő

ő is Unicode U+0151, named LATIN SMALL LETTER O WITH DOUBLE ACUTE. It is used in Hungarian. Two slanted lines above a vowel, found only in Hungarian: ő and ű are the long forms of ö and ü. See the ő 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.
