+ * 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 other words, if there are chars in a string with char code above 255, we

+ * 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).

+ // 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.
