Write a method like Python's string.printable in Groovy

#groovy

To find out if a string has only printable characters, Python has a function called string.printable. We can make our own String.isPrintable() using metaprogramming in Groovy.

import java.nio.charset.Charset String.metaClass.isPrintable = { return Charset.forName("US-ASCII") .newEncoder() .canEncode(delegate) } assert 'Abc'.isPrintable() == true assert 'àé'.isPrintable() == false assert 'môre'.isPrintable() == false assert 'de076'.isPrintable() == true
