Latin character I with tilde
About this character
The character ĩ is known as Latin character I with tilde and carries the Unicode code point U+0129, which is 297 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, ĩ takes 2 bytes in UTF-8 (0xC4 0xA9) and 1 in UTF-16 (0x0129). 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 ĩ?
Its code point is U+0129, which is 297 in decimal and 0451 in octal. In HTML you can write it as ĩ or ĩ.
Why does ĩ show up as a box or a question mark?
An empty box means the font has no glyph for U+0129. 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 ĩ in a filename, a URL or a password?
In a URL it must be encoded as %C4%A9. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
