Motivation
Closes: #9771
The current lexer for the SFN v2 interpreter occasionally encounters difficulty accurately lexing string literals declared as arguments within intrinsic functions. This pull request (PR) resolves this issue within the lexer by implementing a non-greedy approach to token consumption between quotes. This involves defining safe code points that exclude the specified quote delimiters, and appropriately associating escaped character symbols with their intended counterparts (\n, \r, \t).
Changes
Relevant updates to the intrinsic function lexer. Escape characters replacement in intrinsic function preprocessor. Relevant tests.
