Frequently asked questions
- What's the difference between ASCII and Unicode code points here?
- ASCII only covers code points 0-127 (basic English letters, digits, punctuation). This tool works with full Unicode code points, so it also handles accented letters, emoji, and characters from any script. Each shown as its decimal or hex value.
- How are emoji and multi-byte characters handled?
- Each character is converted by its actual Unicode code point, not by byte. An emoji like 😀 is one code point (U+1F600), not four separate bytes, so the conversion stays accurate even for characters outside the ASCII range.
- Can I convert code points back into readable text?
- Yes, paste a list of decimal or hex values (like 72 101 108 108 111 or U+0048 U+0065...) and the tool reconstructs the original string.
