I write a regex code in registration model but when i input in formik form field with bangla font, regex express can't validate bangla unicode value.

import * as Yup from "yup";
const banglaLang = /^([A-Za-z]|\p{InBengali})$/i;
class RegisterModel {
  /**
   * Model properties
   */
  constructor() {
    this.employeeNameBn = "";
  }

  /**
   * Validator schema
   */
  validator() {
    return Yup.object().shape({
      employeeNameBn: Yup.string()
        .required("user full name (in Bangla) is a required field")
        .matches(banglaLang, "Please type in bangla"),
    });
  }
}

export const Register = new RegisterModel();

CodePudding user response：

You can use

/^[\p{sc=Bengali}\s] $/u;

Details:

• ^ - start of string
• [\p{sc=Bengali}\s] - one or more occurrences of
  • \p{sc=Bengali} - a Bengali char
  • \s - a whitespace char
• $ - end of string
• u - a flag that allows the use of Unicode property classes like \p{...}.

See the regex demo.
