How to trim no-break space in Java?

While   is a non breaking space (a space that does not want to be treated as whitespace), you can trim a string while preserving every   within the string with a simple regex:

string.replaceAll("(^\\h*)|(\\h*$)","")

• \h is a horizontal whitespace character: [ \t\xA0\u1680\u180e\u2000-\u200a\u202f\u205f\u3000]

If you are using a pre JDK8 Version, you need to explicitly use the list of chars instead of \h.
