Scala: matching special characters

Question

In Scala I need to test if a string has any of the following 'special' characters: !@#\\$^%&*()_-\\+={}[]|;:"'<,>.?/

I can not simply use 'nonword' "\\\\W" regex for this because string may have Cyrillic characters that regex "\\\\W" matches as well. Trying to use regex:

new Regex("""~`!@#\$^%&*()_-\+={}[]|;:"'<,>.?/""")

results in exception:

 java.util.regex.PatternSyntaxException: Illegal repetition near index 17 ~`!@#\$^%&*()_-\+={}[]|;:"'<,>.?/
                                                                                           ^

at java.util.regex.Pattern.closure(Pattern.java:3104)
at java.util.regex.Pattern.sequence(Pattern.java:2101)

Any ideas?

You need to put all the special characters into character class.

[~!@#$^%&*\\(\\)_+={}\\[\\]|;:\"'<,>.?`/\\\\-]

If you want to add space also, then it should be

[~!@#$^%&*\\(\\)_+={}\\[\\]|;:\"'<,>.?` /\\\\-]
