Prefer Ů in HTML markup — the capital U in the name matters. Numeric forms and typing Ů in UTF-8 also work. For the lowercase letter, use ů (ů).
Å (Å) is A with a ring. Ů is U with a ring — same mark shape, different base letter.
vs Ū
Not a macron
Ū (Ū) has a horizontal bar above. Ů has a circular ring — different marks.
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
\016E belongs in CSS strings. Ů / Ů / Ů belong in HTML.

Use real language context
