2. Direct: typing W in a UTF-8 file is the simplest and preferred approach.

4. Sentence: shows ordinary text use — no entity required for everyday letters.
Pitfalls & Tips
Common mistakes when working with this character.
Prefer
Type W in body text
ASCII letters do not need entities for normal reading. Prefer typing W directly.
Named?
No named entity
HTML5 does not define a named entity for U+0057. Use numeric forms when an entity is required.
Look-alikes
Not W circumflex or wynn
Ordinary W is U+0057. Ŵ (U+0174) has a circumflex. Ƿ (U+01F7) is capital wynn — a different letter.
Case
Use the correct case
Lowercase is w (U+0077). Do not mix case when casing matters for identifiers or display.
CSS
Pad the CSS escape
Use \0057 (not bare \57) so a following digit is not absorbed into the escape.
Semicolon
End references
Always finish with ; — write W, not W.
