Function: parseSpecificCharacterSet()

parseSpecificCharacterSet(bytes): readonly string[]

Parse a (0008,0005) Specific Character Set value (a CS, possibly multi-valued via ``) into its trimmed defined terms.

The first value may be empty (the ISO-2022 "G0 starts as ISO_IR 6" rule); it is preserved as "" rather than dropped so resolveDecoderLabel can apply the default-repertoire fallback.

A component this closed table does not name is not a defined term, and it is withheld rather than returned. This value is multi-valued on the backslash, every component is a string a sender authored, and the result lands on Element.specificCharacterSet, where it presents itself as an identifier a downstream package may interpolate: that is the field, and the delimiter, this package's measured PHI leak ran through. Decoding is unaffected, because resolveDecoderLabel already skipped any term it could not map and skips the withheld marker for the same reason.

Parameters

bytes

Buffer

Returns

readonly string[]

Example

import { parseSpecificCharacterSet } from "@cosyte/dicom";
// bytes for "ISO 2022 IR 6\\ISO 2022 IR 87"
const terms = parseSpecificCharacterSet(buf);
