Apparently got stuck with the simple task to validate an entry with any PRINTABLE characters (ASCII between 32 and 126) using search (or any other) method. Something like:
if (str.search( . . . ) != -1)
I was thinking more like using Predefined Sets, i.e. [print:]
or [:graph:]. but nobody really gives any examples of syntax with those things.
Any idea would be greatly appreciated!!!
