Como eliminar caracteres no imprimibles de una variable de texto

Hi Pedro,

if your text is in a Uniface variable you could take a look at this example.

Hope it helps.

Hola, ese ejemplo no me sirve lo que necesito es eliminar los caracteres no imprimibles de una variable string de Uniface. Yo recuerdo que existía una función o comando en Uniface que lo hacía. Pero no lo encuentro o lo eliminaron

Saludos

Hi Pedro,

the example I suggested is using $replace() to delete NUL values (binary ZERO, a not printable character) from a raw variable; it could obviously be used against a string variable too.
Is your case different?
Could you give us an example?

Hi

maybe just converting the string variable to raw and replacing these chars.

rawVariable = $encode("URAW", stringVariable)

replacing "aliens" by nothing or a space. For instance,

rawVariable = $replace(rawVariable, 1, "{;", " ", -1) ;char SUB (=soft EOF)

stringVariable = $encode("USTRING", rawVariable)
