I want to restrict the first and last name to be Latin characters only. So I added the following
<ClaimType Id="givenName">
<UserHelpText>First name must be in English.</UserHelpText>
<Restriction>
<Pattern RegularExpression="^[\u0020-\u007E\u00A0-\u00FF]*$" HelpText="First name must be in English." />
</Restriction>
</ClaimType>
The problem is when the user signs up and enters non-Latin characters, the message being displayed is "Please match the requested format: Your first name". I have not defined this message in my policy.
Is there any other attribute in the XML where I can define the message I would like to display ("First name must be in English.")
