Hi Alexey, The following param in the Virtuoso INI file controls the handling of the backslash character:
SQL_NO_CHAR_C_ESCAPE=0
This options is 0 by default and can be either 1 or 0. This option controls
Virtuoso's interpretation of the backslash in PL text which is normal
interpreted as escaping rather than literal.
