\n \r \t Matches a newline, a carriage return, and a tab character respectively.
Some characters assume a special meaning when positioned in a specific position of the pattern (see
Table 8 - 6 ); when you have to match the symbol and not use its special meaning, you have to escape the
character with the backslash \ prefix. Note that if you use the regex special syntax, the slash character /
must also be properly escaped; this character has no special meanings in the pattern definition but it is
used as a terminator for the regular expression.

In the following example, a character class is used to define a pattern that matches any phrase that
contains one vowel:
class Main
{
public static function main()
{
var re = ~/[aeiou]/;
trace(re.match(???haXe??™)); // true
trace(re.match(???xxx??™)); // false
}
}
In the character class the dash symbol ( - ) can be used to create ranges of values. In this case, the pattern
matches any phrase that contains two hexadecimals in sequence.
