Latin character U with tilde
About this character
The character ũ is known as Latin character U with tilde and carries the Unicode code point U+0169, which is 361 in decimal. It belongs to the Latin Extended-A block (U+0100–U+017F), which gathers the accented letters of Central and Northern European languages missing from Latin-1, such as Polish, Czech and Hungarian.
In memory, ũ takes 2 bytes in UTF-8 (0xC5 0xA9) and 1 in UTF-16 (0x0169). 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 ũ?
Its code point is U+0169, which is 361 in decimal and 0551 in octal. In HTML you can write it as ũ or ũ.
Why does ũ show up as a box or a question mark?
An empty box means the font has no glyph for U+0169. 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 ũ in a filename, a URL or a password?
In a URL it must be encoded as %C5%A9. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
