Frequently Asked Questions
Does this handle accented and Turkish characters correctly?
Yes - it uses locale-aware casing, so characters like ı/İ, ş, ğ, ö, ü, ç convert correctly instead of falling back to plain ASCII rules.
Is my text sent to a server?
No, the conversion happens entirely in your browser.
