String type min\maxLength validation error for multibyte strings values

[burkun-sergey]

Incorrect string type minLength\maxLength validation with multibyte string values.

Raml example:

#%RAML 1.0 DataType
type: string
description: IATA
minLength: 3
maxLength: 3
example: MOW

To fix the issue you can replace strlen() with mb_strlen() in StringType::validate()

        if (null !== $this->minLength) {
            if (\mb_strlen($value) < $this->minLength) {
                $this->errors[] = TypeValidationError::stringLengthExceedsMinimum($this->getName(), $this->minLength, $value);
            }
        }
        if (null !== $this->maxLength) {
            if (\mb_strlen($value) > $this->maxLength) {
                $this->errors[] = TypeValidationError::stringLengthExceedsMaximum($this->getName(), $this->maxLength, $value);
            }
        }
