Hi,
There might be some whitespace except " "(0x20) character.
Can you try the following steps?
First, normalize whitespace in both variables using Assign activities.
strNomeClienteInput = System.Text.RegularExpressions.Regex.Replace(NomeClienteInput.ToString,"\s+"," ").Trim
strNomeOutput = System.Text.RegularExpressions.Regex.Replace(NomeOutput.ToString,"\s+"," ").Trim
Then, check with the following expression
strNomeOutput.Equals(strNomeClienteInput)
Regards,
