@SAFECHARSINFO — Returns internal plugin info.

Syntax:
%@SAFECHARSINFO[n,text]

nselects the plugin info to return:
     0: the plugin version number; parts separated by periods
     1: a 12-digit hex (i.e. 96-bit) bitmap of current “unsafe” characters
     2: return text made safe according to the current settings

This function is intended for use by other plugins. Most users will never need it; it is of little or no use in batch files or at the command line.
