pydicom.charset.decode_bytes(value: bytes, encodings: Sequence[str], delimiters: set[int]) str[source]

Decode an encoded byte value into a unicode string using encodings.

  • value (bytes) – The encoded byte string in the DICOM element value.

  • encodings (list of str) – The encodings needed to decode the string as a list of Python encodings, converted from the encodings in (0008,0005) Specific Character Set.

  • delimiters (set of int) – A set of characters or character codes, each of which resets the encoding in value.


The decoded unicode string. If the value could not be decoded, and reading_validation_mode is not RAISE, a warning is issued, and value is decoded using the first encoding with replacement characters, resulting in data loss.

Return type:


  • UnicodeDecodeError – If reading_validation_mode is RAISE and value could not be decoded with the given encodings.

  • LookupError – If reading_validation_mode is RAISE and the given encodings are invalid.
