If the above case was the issue then you can validate the field using JS by using the below code,

function validateTextWithSpecialChars(inputText, allowedSpecialChars) {  const pattern = new RegExp(`^[A-Za-z${escapeRegExp(allowedSpecialChars)}]+$`);  return pattern.test(inputText);}function escapeRegExp(string) {  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');}$parameters.IsTextWithAllowedSpecialCharacters = validateTextWithSpecialChars($parameters.UserText, $parameters.SpecialCharacters)

here, the thing is you have to pass an input parameter which contains the special character you have stored in the database.

Hope it helps.

Hi Nandhakuma,

No, the user can enter alpha numeric text but if user wants to enter special characters or accent number

Eg: text:-  hdhe& is allowed cause & it is there in database

Text:- gigd* not allowed cause * sogn is not present in database.
