* 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).

* API.text() function sets (unless you overwrite it with manual values
* given to API.text(.., flags) )

* 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
* .noBOM
