Frequently asked questions
How do I find invisible characters in a string?
Paste the text into the Inspector tab to see every character with its code point, HTML entities, UTF-8 bytes, UTF-16 units and category. The Bidi / Invisible tab focuses on invisible and bidirectional control characters.
How can I tell if two identical-looking strings are different?
Inspect both in the Inspector tab. The Confusable Detector tab also highlights lookalike characters, such as a Cyrillic letter that resembles a Latin one.
How do I normalize a string to NFC, NFD, NFKC or NFKD?
Use the Normalizer tab and pick the normalization form.
How do I convert text to \uXXXX or HTML entity escapes?
The Escape Sequences tab encodes and decodes \uXXXX, %uXXXX and HTML-entity forms.
Can I convert emoji to :shortcode: names?
Yes, the Emoji ↔ Shortcode tab converts between emoji and GitHub-style :shortcode: names.
