Not the same ũ · Ü · U
Prefer Ũ in HTML markup — the capital U in the name matters. Numeric forms and typing Ũ in UTF-8 also work. For the lowercase letter, use ũ (ũ).
Ü (Ü) has two dots (diaeresis). Ũ has a tilde — different marks and languages.
vs U
Not plain capital U
Keyboard U is U+0055. Use U+0168 only when you need the tilde form.
Encoding
Keep UTF-8 declared
Latin Extended-A letters display reliably with <meta charset="UTF-8">. Prefer named entities when the source file encoding is uncertain.
CSS vs HTML
Do not mix escapes
\0168 belongs in CSS strings. Ũ / Ũ / Ũ belong in HTML.

Use real language context
When Ũ appears in Vietnamese words, keep surrounding text and lang accurate (for example vi) so screen readers get useful context.
