Unicode Sorting & Collation Tool

Sort text correctly according to Unicode rules. Compare how different languages and locales order characters, from accents to case sensitivity.

How the Unicode Sorting Tool Works

Enter a list of text items to sort, one per line. Choose the sorting method: code point order, locale-aware, case-sensitive or insensitive, natural sort, or custom collation.

Unicode sorting considers character properties beyond simple ASCII values. Accented characters, case folding, and locale-specific rules affect sort order. The tool applies Unicode Collation Algorithm (UCA) rules.

Preview the sorted results instantly. Compare different sorting methods side by side. Export the sorted list. Essential for internationalized applications.

When You'd Actually Use This

Sorting international names

Customer names from different countries? Sort correctly with locale-aware sorting. Ä sorts differently in German vs Swedish. Get it right for each locale.

Building multilingual apps

Your app displays sorted lists. Implement proper Unicode sorting. Test against this reference. Ensure correct order in all languages.

Preparing bibliographies

Academic references with international authors? Sort according to style guidelines. Handle diacritics correctly. Professional bibliography preparation.

Organizing multilingual content

Content in multiple languages? Sort each language appropriately. Locale-specific sorting respects language rules. Better user experience.

Testing sort implementations

Built a sorting algorithm? Test against this reference. Verify Unicode compliance. Catch edge cases with special characters.

Data cleaning and normalization

Deduplicate lists with proper sorting. Similar names sort together. Identify near-duplicates for review. Clean data more effectively.

What to Know Before Using

Sort order varies by locale.German: Ä sorts like Ae. Swedish: Ä sorts after Z. Spanish: CH was once a separate letter. Locale determines correct order.

Case sensitivity matters.Case-sensitive: 'Z' before 'a'. Case-insensitive: 'a' before 'Z'. Choose based on your needs. Affects sort results.

Natural sort handles numbers.'file2' before 'file10' in natural sort. Code point sort: 'file10' before 'file2'. Natural sort is more human-friendly.

Diacritics affect sorting.Some locales ignore diacritics (é = e). Others sort them specially. Know your locale's rules for correct sorting.

Pro tip: For databases, use collation settings that match your users' locale. UTF-8 alone isn't enough. Collation determines sort order. Choose carefully during schema design.

Common Questions

What is Unicode sorting?

Sorting text according to Unicode rules. Considers character properties, not just byte values. Handles international characters correctly.

Why doesn't ASCII sort work?

ASCII sort uses byte values. 'Z' (90) before 'a' (97). Accented chars sort unpredictably. Unicode sorting respects language rules.

What's natural sorting?

Numbers in strings sort numerically. 'file2' before 'file10'. More intuitive than character-by-character comparison.

How do I sort emoji?

Emoji sort by code point. Grouped by category in Unicode. Not particularly meaningful. Consider custom ordering for emoji.

What's the Unicode Collation Algorithm?

UTS #10 defines Unicode sorting. Multiple comparison levels (base, accent, case). Locale-specific tailoring. Industry standard.

Can I sort right-to-left text?

Yes, but sort order is logical, not visual. Arabic and Hebrew sort by their code points. Locale settings affect collation.

How do I handle mixed scripts?

Sort by script first, then within script. Or use a common collation. Depends on your use case. Consider user expectations.
