- * 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)
- * or a JS object, where key = sourceCharCode, value = outputCharCode
- * missing keys will be treated as: sourceCharCode === outputCharCode

- // I am not an expert on the topic, and I don't want to write a thesis.
- // 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.
