How can I accurately match accented characters (diacritics) in a JavaScript regular expression for names?

Concrete JavaScript Regular Expression for Accented Characters (Diacritics)

Your aim is to match accented characters (diacritics) in a JavaScript regular expression for a last_name, first_name format. Here are three approaches you suggested:

1. Explicitly Listing Accented Characters

This approach is restrictive and inefficient. Maintaining an accurate list of accented characters can be challenging, and the expression becomes unnecessarily complex.

2. Using the . Character Class

Although concise, the . character class matches any character except the newline, leading to potential inaccuracies in matching. It's not an ideal solution for diacritics.

3. Unicode Range

Using the Unicode range u00C0-u017F effectively matches the accented characters within the Latin character set. This approach is suitable for your scenario where faculty names are expected to be in Latin characters.

Best Approach

For your specific requirements, the third approach with the Unicode range is most appropriate. It provides a precise and efficient way to match diacritics.

Alternative Approach

A simplified approach that encompasses most accents is:

[A-zÀ-ú] // lowercase and uppercase characters

Unicode Character Table

Refer to the Unicode Character Table to verify the characters included in the Unicode ranges:

• [Unicode Basic Latin](https://www.unicode.org/charts/PDF/U0000.pdf)
• [Unicode Latin-1 Supplement](https://www.unicode.org/charts/PDF/U0080.pdf)
