Free online functions: steps and checks

Encode Unicode Escape Text for Free

Paste text and encode its characters into Unicode escape sequences for inspection or copying. Review common BMP characters in the output and check supplementary characters separately, since many emoji require correctly paired surrogates.

Decode Backslash-u Escapes for Free

Enter text containing supported backslash-u sequences and choose decoding to view the represented characters. Compare the decoded result with the intended wording, paying extra attention to surrogate pairs and any sequences left unchanged.

Convert Unicode Text Online for Free

Switch between text and supported Unicode escapes to inspect character representation in a copied string. Check accents and emoji after conversion; supplementary characters need additional review beyond the encoder's common BMP handling.
