         * 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
         * flags.noBOM = true
         *
         * ===================================================================================
         * `flags` properties relied upon:
         *   .sourceEncoding = string with encoding label.
         *                     "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
         *                     (must be supported by jsPDF font metrics, otherwise no encoding)
