The preprocessor escaped string operator
##"//text//"##
The string literal containing escape characters

{{fbdoc item="desc"}}
This operator explicitly indicates that the string literal following it (wrapped in double quotes) should be processed for escape sequences. This a preprocessor operator and can only be used with string literals at compile time.

The default behavior for string literals is that they not be processed for escape sequences. ##[[KeyPgOptionescape|Option Escape]]## can be used in the //[[CompilerOptlang|-lang fblite]]// dialect to override this default behaviour causing all strings to be processed for escape sequences.

Use the [[KeyPgOpPpNoescape|$ operator (Non-Escaped String Literal)]] operator to explicitly indicate that a string should not be processed for escape sequences.
