Latin character U with grave accent
About this character
The character ù is known as Latin character U with grave accent and carries the Unicode code point U+00F9, which is 249 in decimal. It belongs to the Latin-1 Supplement block (U+0080–U+00FF), which gathers the accented letters of Western European languages along with the punctuation and symbols inherited from ISO 8859-1.
In memory, ù takes 2 bytes in UTF-8 (0xC3 0xB9) and 1 in UTF-16 (0x00F9). That difference is why badly configured forms or databases garble this character: they assume one byte per character.

Frequently asked questions
What is the Unicode code for ù?
Its code point is U+00F9, which is 249 in decimal and 0371 in octal. In HTML you can write it as ù or ù.
Why does ù show up as a box or a question mark?
An empty box means the font has no glyph for U+00F9. The character is still in the text: switching to a font that covers the block (Noto, DejaVu or Segoe UI Symbol) makes it appear.
Can I use ù in a filename, a URL or a password?
In a URL it must be encoded as %C3%B9. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
