ASCII to Unicode Converter
Decode \uXXXX ASCII-safe escape sequences back to Unicode text, live as you type.
Decodes standard \uXXXX escape sequences (the ASCII-safe format many serialization formats use) back to readable Unicode text — also accepts the \u{XXXXX} form for characters beyond the Basic Multilingual Plane. Converts live as you type, entirely in your browser.

What is ASCII to Unicode Converter?
Paste \uXXXX (or \u{XXXXX}) escape sequences — the ASCII-safe format many serialization formats and config files use to represent characters that aren't in the plain 0-127 ASCII range — and get the decoded Unicode text instantly. Handy for reading a `.properties` file, a JSON string with escaped characters, or any log line that was written out in escaped form instead of raw Unicode. Both escape styles are recognized: the standard 4-digit \uXXXX form and the \u{XXXXX} form used for characters beyond the Basic Multilingual Plane (most emoji, for instance). Decoding happens live as you type, entirely in your browser — nothing you paste is sent to a server. If no valid escape sequences are found, the field is flagged instead of silently returning nothing.
FAQ
Standard 4-digit \uXXXX escapes and the \u{XXXXX} form used for characters outside the Basic Multilingual Plane.
That's fine — only the \uXXXX / \u{XXXXX} sequences are decoded, and any plain characters in between are passed through unchanged.
Use the paired Unicode to ASCII Converter, which encodes plain text into \uXXXX escape sequences.
