/**
 * Workaround for oxc printer lone-surrogate bug (https://github.com/oxc-project/oxc/issues/3526).
 * The oxc codegen replaces lone surrogates (0xD800-0xDFFF) with U+FFFD in long CJS strings,
 * corrupting ANTLR ATN serialized data which uses surrogates as raw char codes.
 * This plugin converts the string literals to numeric char code arrays before the printer
 * sees them. Can be removed once the upstream fix fully covers CJS long strings.
