Function: resolveCharset()

resolveCharset(raw): CharsetResolution

Resolve an MSH-18 label (or an options.charset override) to a CharsetResolution. A blank / undefined label resolves to the ASCII default. A recognized Table-0211 code returns its registry entry. An unrecognized label resolves to a verbatim, recognized: false outcome so the caller preserves bytes and emits UNKNOWN_CHARSET.

Parameters

raw

string | undefined

Returns

CharsetResolution

Example

import { resolveCharset } from "@cosyte/hl7";
resolveCharset("UNICODE UTF-8"); // { canonical: "UTF-8", treatment: "decode", ... }
resolveCharset("ISO IR87");      // { canonical: "ISO IR87", treatment: "verbatim", recognized: true }
resolveCharset("WINDOWS-1252");  // { canonical: "WINDOWS-1252", treatment: "verbatim", recognized: false }
