OptionalfatalControls error handling behavior when invalid Modified UTF-8 byte sequences are encountered.
When true, the decoder throws a TypeError immediately upon encountering invalid bytes. When false, invalid
sequences are replaced with the Unicode replacement character (U+FFFD).
OptionalignoreWhether to ignore the Byte Order Mark (BOM) at the beginning of the input.
When false, a BOM (0xEF 0xBB 0xBF) at the start of the input is treated as a zero-width non-breaking space
character. When true, the BOM is silently ignored and not included in the decoded output.
