Re: In 2013, there are still programs with huge Unicode bugs :-(

And how many web forms forget to check the presence of a percent sign
and are executing SQL searches without cheking it using clauses
similar to "WHERE table.field LIKE :parameter" by binding directly the
submitted form value to the "parameter" variable placeholder, ignoring
the fact that the percent sign in the right operand of a LIKE is
parsed specially by the SQL engine ?

Same thing about programs using submitted values directly (or
concatenatng them) to create any kind of regular expressions, or to
generate a SQL statement (with the security issue of possible SQL
injection to retrieve confidential data, by terminating the query
statement with a quote, a semicolon, and initiating a seonf statement
which could even drop the full database or alter any other tables in
that database ?).
