HTML Entity - O With Diaeresis (umlaut)

Mistake: Using plain ASCII letters instead of accented characters in foreign words

Fix: Always use the correct accented character for proper spelling: 'jalapeño' not 'jalapeno', 'façade' not 'facade'. Use HTML entities when the character is not directly available on your keyboard.

Mistake: Confusing similar-looking accented characters like á (a-acute) vs à (a-grave)

Fix: Acute (á) tilts right and is used in Spanish, French. Grave (à) tilts left and is used in Italian, Catalan. Verify the correct accent for the language you're writing.

Mistake: Forgetting to include diacritics in SEO titles and meta descriptions

Fix: Search engines correctly index accented characters. Using proper accents in titles improves relevance for language-specific searches.
