%5E is the URL-encoded caret (^).
In a URL, %5E stands for the caret (^). Here is when to encode it, what it does in each part of a URL, and what every major language outputs.
Quick facts
| Character | ^ |
|---|---|
| Name | Caret |
| Unicode | U+005E |
| UTF-8 bytes | 5E (1 byte) |
| Percent-encoded | %5E |
| Lowercase form | %5e — identical meaning |
| Double-encoded | %255E |
| HTML form encoding | %5E |
| RFC 3986 class | Not allowed in URLs |
What it means in a URL
Not allowed raw; encoded as %5E. Every encoder in the comparison table encodes it. It turns up in search queries, version ranges (^1.2.0) and maths expressions.
RFC 3986 class: Not allowed in URLs. It is outside the characters RFC 3986 permits, so it must always be percent-encoded.
When to encode it
| Where it appears | What to do |
|---|---|
| Path segment | Encode |
| Query value | Encode |
| Fragment | Encode |
| Form body | Encode |
The mistake to watch for
Version strings such as ^1.2.0 in npm-style query parameters, which some servers reject unless encoded.
What each language produces
Every function in this table encodes it. Output for the single character, UTF-8 input, tested against the real runtimes (see the encoding comparator for your own strings).
| Function | Output | |
|---|---|---|
| JavaScript encodeURIComponent(s) | %5E | encoded |
| JavaScript encodeURI(s) | %5E | encoded |
| JavaScript URLSearchParams | %5E | encoded |
| Python urllib.parse.quote(s) | %5E | encoded |
| Python quote(s, safe="") | %5E | encoded |
| Python urllib.parse.quote_plus(s) | %5E | encoded |
| PHP rawurlencode($s) | %5E | encoded |
| PHP urlencode($s) | %5E | encoded |
| Java URLEncoder.encode(s, UTF_8) | %5E | encoded |
| Go url.QueryEscape(s) | %5E | encoded |
| Go url.PathEscape(s) | %5E | encoded |
| Ruby URI.encode_www_form_component(s) | %5E | encoded |
| Ruby ERB::Util.url_encode(s) | %5E | encoded |
| C# / .NET Uri.EscapeDataString(s) | %5E | encoded |
Decoding it
decodeURIComponent('%5E') returns the caret (^). Python: urllib.parse.unquote('%5E'); PHP: rawurldecode('%5E'). Paste any string into the URL decoder to decode it in your browser.

Common questions.
%5E is the percent-encoded form of the caret (^), whose byte value is 0x5E. Decoding the URL turns it back into the character.
Yes. Hex digits in percent-encoding are case-insensitive, so %5e and %5E mean the same thing. RFC 3986 recommends uppercase, and mixing cases can make caches and analytics count one URL as two.
Use your language’s encoder on the value: encodeURIComponent in JavaScript gives %5E, Python’s quote(s, safe="") gives %5E, PHP’s rawurlencode gives %5E.
