Privacy details

Unicode escape converter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Unicode escape converter explained

Turn each UTF-16 code unit into a literal backslash-u escape. Characters outside the basic multilingual plane use a high and low surrogate pair, so the output can be pasted into a JSON or JavaScript string.

A worked example

A becomes \u0041. The octopus emoji becomes \ud83d\udc19 and decodes back to one Unicode character.

Before you use the result

The decoder accepts sequences of \uXXXX escapes, not full JSON strings, braced code-point escapes or a mixture of raw text and escapes.

Next: JSON stringify text
