         * 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

         * flags.autoencode = true
         * flags.noBOM = true

    // However, it is good to outline here the basic algorithm and the few data
    // structures and optimizations here that make this implementation fast.
    // The basic idea behind LZW is to build a table of previously seen runs
    // addressed by a short id (herein called output code).  All data is
    // referenced by a code, which represents one or more values from the
    // original input stream.  All input bytes can be referenced as the same
    // value as an output code.  So if you didn't want any compression, you
    // could more or less just output the original bytes as codes (there are
    // some details to this, but it is the idea).  In order to achieve
    // compression, values greater then the input range (codes can be up to
    // 12-bit while input only 8-bit) represent a sequence of previously seen
    // inputs.  The decompressor is able to build the same mapping while
    // decoding, so there is always a shared common knowledge between the
    // encoding and decoder, which is also important for "timing" aspects like
    // how to handle variable bit width code encoding.
    //
    // One obvious but very important consequence of the table system is there
    // is always a unique id (at most 12-bits) to map the runs.  'A' might be
    // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc.  This relationship
    // can be used for an effecient lookup strategy for the code mapping.  We
    // need to know if a run has been seen before, and be able to map that run
    // to the output code.  Since we start with known unique ids (input bytes),
    // and then from those build more unique ids (table entries), we can
    // continue this chain (almost like a linked list) to always have small
    // integer values that represent the current byte chains in the encoder.
    // This means instead of tracking the input bytes (AAAABCD) to know our
    // current state, we can track the table entry for AAAABC (it is guaranteed
    // to exist by the nature of the algorithm) and the next character D.
    // Therefor the tuple of (table_entry, byte) is guaranteed to also be
    // unique.  This allows us to create a simple lookup key for mapping input
    // sequences to codes (table indices) without having to store or search
    // any of the code sequences.  So if 'AAAA' has a table entry of 12, the
    // tuple of ('AAAA', K) for any input byte K will be unique, and can be our
    // key.  This leads to a integer value at most 20-bits, which can always
    // fit in an SMI value and be used as a fast sparse array / object key.
