locale property in alpha validator is not validating for all Alphabet locales.

[Ushmidave]

Describe the bug

while localizing the validation using different types of validation locales, only greek and spanish words are validated when input formControl is been initialized with their respective language words as below:

 this.addressInfoFormGroup = this.formBuilder.group({
            danishName:['år', RxwebValidators.alpha({locale:ValidationAlphabetLocale.danish })           
            ], 
            germanName:['lächeln',RxwebValidators.alpha({locale:ValidationAlphabetLocale.german})],
            greekName:['φιλοξενία',RxwebValidators.alpha({locale:ValidationAlphabetLocale.greek})],
            russian:['Привет',RxwebValidators.alpha({locale:ValidationAlphabetLocale.russian})],
            french:['Garçon',RxwebValidators.alpha({locale:ValidationAlphabetLocale.russian})],
            spanish:['Gracías',RxwebValidators.alpha({locale:ValidationAlphabetLocale.spanish})]
        });

Expected Behavior

Localization in alpha validation should validate the following alphabet locales when its respective language word is set as value of the formControl
