Latin character regex

[CodilX]

hi there,

i'm having troubles with my regex..

i have a name input field, and the regex for it is:

var first_nameRegex = /^[a-zA-Z]+(([\'\,\.\- ][a-zA-Z ])?[a-zA-Z]*)*$/;

how do i change it so that i would allow letters such as ą č ė ę į š ū ų and also in uppercase?

Have you tried just checking for

[[:alpha:]]

? Or, does that include too many?
