Frequently Asked Questions

Why would I lowercase text?

Most often to normalise it before comparing or deduplicating. Email addresses, tags, usernames and URLs are usually stored lowercase so that two entries differing only in case are treated as the same.

Does lowercasing lose information?

Yes — the original capitalisation cannot be recovered. Keep the original if you may need to display it later, and store the lowercase form only as a comparison key.

Is lowercasing safe for all languages?

Mostly, but there are locale traps. Turkish has a dotless ı and a dotted İ, so the naive mapping is wrong there. Greek final sigma also depends on position in the word.
