                 * "For text strings encoded in Unicode, the first two bytes must be 254 followed by
                 * 255, representing the Unicode byte order marker, U+FEFF. (This sequence conflicts
                 * with the PDFDocEncoding character sequence thorn ydieresis, which is unlikely
                 * to be a meaningful beginning of a word or phrase.) The remainder of the
                 * string consists of Unicode character codes, according to the UTF-16 encoding
                 * specified in the Unicode standard, version 2.0. Commonly used Unicode values
                 * are represented as 2 bytes per character, with the high-order byte appearing first
                 * in the string."
                 *
                 * In other words, if there are chars in a string with char code above 255, we
                 * recode the string to UCS2 BE - string doubles in length and BOM is prepended.
                 *
                 * HOWEVER!
                 * Actual *content* (body) text (as opposed to strings used in document properties etc)
                 * does NOT expect BOM. There, it is treated as a literal GID (Glyph ID)
                 *
                 * Because of Adobe's focus on "you subset your fonts!" you are not supposed to have
                 * a font that maps directly Unicode (UCS2 / UTF16BE) code to font GID, but you could
                 * fudge it with "Identity-H" encoding and custom CIDtoGID map that mimics Unicode
                 * code page. There, however, all characters in the stream are treated as GIDs,
                 * including BOM, which is the reason we need to skip BOM in content text (i.e. that
                 * that is tied to a font).
                 *
                 * To signal this "special" PDFEscape / to8bitStream handling mode,
                 * API.text() function sets (unless you overwrite it with manual values
                 * given to API.text(.., flags) )
                 * flags.autoencode = true

                 *                     "Unicode" by default. = encoding of the incoming text.
                 *                     pass some non-existing encoding name
                 *                     (ex: 'Do not touch my strings! I know what I am doing.')
                 *                     to make encoding code skip the encoding step.
                 *   .outputEncoding = Either valid PDF encoding name
