Not here. This follows decodeURIComponent. Replace + with %20 if you need space decoding from application/x-www-form-urlencoded.

Incomplete % sequences or invalid UTF-8 after decoding.

How it works

Percent triplets are decoded to bytes, then interpreted as UTF-8.

+ is treated as a literal plus (decodeURIComponent does not map + to space).

Read query strings copied from network tools or logs.

Decoded content can include scripts or sensitive data; handle it carefully.

Plus to space?: Not here. This follows decodeURIComponent. Replace + with %20 if you need space decoding from application/x-www-form-urlencoded.
Why errors?: Incomplete % sequences or invalid UTF-8 after decoding.
Full URLs?: Paste only the encoded component; full URLs may need parsing first.
