/**

* Pattern that makes it easy to distinguish whether a region has a single
|
|
* international dialing prefix or not. If a region has a single international
|
|
* prefix (e.g. 011 in USA), it will be represented as a string that contains
|
|
* a sequence of ASCII digits, and possibly a tilde, which signals waiting for
|
|
* the tone. If there are multiple available international prefixes in a
|
|
* region, they will be represented as a regex string that always contains one
|
|
* or more characters that are not ASCII digits or a tilde.
