/**
 * Encodes a JavaScript string to PDFDocEncoding bytes.
 *
 * PDFDocEncoding is the default encoding for PDF strings:
 * - Bytes 0-127: Standard ASCII
 * - Bytes 128-159: Special Unicode characters (see PDF spec)
 * - Bytes 160-255: ISO Latin-1 (ISO 8859-1)
 *
 * @param str - The string to encode.
 * @returns The encoded byte array.
 *
 * @example
 * ```typescript
 * // Encode "Hello" (ASCII)
 * encodeToPDFDocEncoding('Hello')
 *
 * // Encode with special character (bullet → 0x80)
 * encodeToPDFDocEncoding('H•i')
 * ```
