• Added detection of UTF-16 byte signatures without a byte order mark (BOM) in both modes.
• Added the maxPrescanBytes option to configure the HTML <meta> scan limit, defaulting to 1024 bytes and accepting Infinity to scan the entire input or 0 to skip meta scanning.

• Fixed HTML encoding sniffing to ignore <meta> tags whose closing > is missing or falls beyond the prescan limit.
