text
This object contains lexing functionality relevant to the parsing of text. This is sub-divided into different categories:
string literals (both with escapes and raw)
multi-line string literals (both with escapes and raw)
character literals
These contain the relevant functionality required to specify the degree of unicode support for the underlying language, from ASCII to full UTF-16.

This is a collection of parsers concerned with handling character literals.
This is a collection of parsers concerned with handling character literals.
Character literals are described generally as follows:
desc.textDesc.characterLiteralEnd: the character that starts and ends the literal (for example in many languages this is')desc.textDesc.graphicCharacter: describes the legal characters that may appear in the literal directly. Usually, this excludes control characters and newlines, but permits most other things. Escape sequences can represent non-graphic charactersdesc.textDesc.escapeSequences: describes the legal escape sequences that that can appear in a character literal (for example\nor\u000a)
Aside from the generic configuration, characters can be parsed in accordance with varying levels of unicode support, from ASCII-only to full UTF-16 characters. Parsers for each of four different vareties are exposed by this object.

This is a collection of parsers concerned with handling multi-line string literals.
String literals are described generally as follows:
desc.textDesc.multiStringEnds: the sequence of characters that can begin or end a multi-line string literal. Regardless of which of these is used for a specific literal, the end of the literal must use the same sequencedesc.textDesc.graphicCharacter: describes the legal characters that may appear in the literal directly. Usually, this excludes control characters and newlines, but permits most other things.
