2. Named:Ĩ is the readable HTML5 alias for the same code point.

4. Language sample:lang="ki" marks Kikuyu context for assistive tech and hyphenation.
Pitfalls & Tips
Common mistakes when working with this character.
Named
Prefer Ĩ
The named entity is easier to read than numeric forms. Keep the trailing semicolon.
Look-alikes
Not plain I
U+0128 includes the tilde. Do not replace it with U+0049 when spelling requires Ĩ.
Case
Use the correct case pair
Lowercase is ĩ (U+0129). Named entities are case-sensitive: Ĩ ≠ ĩ.
Combining
Prefer the precomposed form
Use U+0128 rather than I + combining tilde unless you have a specific normalization reason.
CSS vs HTML
Do not mix escapes
\0128 belongs in CSS. Named/numeric entities belong in HTML.
Semicolon
End references
Always finish with ; — write Ĩ, not &Itilde.
