How to generate the payment format based on the country of supplier?

Hi all:

Please give some suggestion about this question.

Background about this question:

When user process the payment via PPR for french supplier, wants to print the check as french amount, example :  Quarante-Quatre Mille Deux Cent Quatre-Vingt-Onze   .

If this is for english supplier,  the check amount display as Forty-Four Thousand Two Hundred Ninety-One.

Is it any possible way to support this?

By the way user is always in English language and doesn't want to switch to different language for this.

Thanks

Michael
