I have a problem with using the **Uniform plugin** and adding “special characters” (for a US perspective) in a `form field`.

Eg., if I insert “André” in a simple `input text field`, I get an error from Uniform saying I have to fill the field out. As soon as I change “André” to “Andre”, everything works.

The field in question is a simple `input text field`, and in the Uniform’s controller I am validating the field with the `alpha` rule.

Is there a way to fix this?

Thanks,  
af

The alpha validator does not validate `André`, as you can see if you put this in a template:

```auto

<?php if(v::alpha('André')) {
  echo 'Yay, valid!';
} ?>

```

You could use `match` with a regular expression or create a custom validator.

I see, thank you.

I think using `match` with a general enough regular expression is the way to go.
