[AlphaCommerceHub] Are the address fields (`Street1`, `Street2`, `City`, `Zip`, `State`) really alphanumeric?

developer.alphacommercehub.com.au/docs/alphahpp-#request-a-paypage-session

So, should the commas, hyphens, brackets be stripped?
What about non-English letters?

I have got a response from AlphaCommerceHub:

• Street 1 and 2 also allow following characters #,.- as well as upper and lower case Latin chars and numbers.

• City is alphanumeric setting

How should my Magento extension pass a dashed city name (like Milton-Freewater, Oregon) to AlphaCommerceHub?
