// binary streams like jpeg image data etc, while stored in JavaScript strings,

// if you, by act of fate

        // UNencode it too, to get back to 16, 32bit or whatever original bin stream.

// Note, Yes, JavaScript strings are, in most cases UCS-2 -
        // 16-bit character arrays. This does not mean, however,
        // that you always have to UTF8 it before base64.
        // it means that if you have actual characters anywhere in
        // that string that have char code above 255, you need to
        // recode *entire* string from 16-bit (or 32bit) to 8-bit array.
        // You can do binary split to UTF16 (BE or LE)
        // you can do utf8, you can split the thing by hand and prepend BOM to it,
        // but whatever you do, make sure you mirror the opposite on
        // the server. If server does not expect to post-process un-base64
        // 8-bit binary stream, think very very hard about messing around with encoding.

// so, long story short:

                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) )
