Request: Add taiwanese style phone number format

[tonywangA]

Hello,

This there a chance to add the phone number format in Taiwan?
The format of the phone number will be like xx-xxx-xxxx or xx-xxxx-xxxx
The format of the mobile phone number will be like xxxx-xxx-xxx
I try to make a check formula below.
(\d{2,3}-?|(\d{2,3}))\d{3,4}-?\d{4}|09\d{2}(\d{6}|-\d{3}-\d{3})|\d{3}-?\d{4}
