[英]Scala: matching special characters
In Scala I need to test if a string has any of the following 'special' characters: !@#\\$^%&*()_-\\+={}[]|;:"'<,>.?/
在Scala中,我需要测试字符串是否具有以下“特殊”字符: !@#\\$^%&*()_-\\+={}[]|;:"'<,>.?/
I can not simply use 'nonword'
"\\\\W"
regex for this because string may have Cyrillic characters that regex "\\\\W"
matches as well. 我不能为此简单地使用'nonword'
"\\\\W"
正则表达式,因为字符串也可能具有与正则表达式"\\\\W"
匹配的西里尔字符。 Trying to use regex: 尝试使用正则表达式:
new Regex("""~`!@#\$^%&*()_-\+={}[]|;:"'<,>.?/""")
results in exception: 结果例外:
java.util.regex.PatternSyntaxException: Illegal repetition near index 17 ~`!@#\$^%&*()_-\+={}[]|;:"'<,>.?/

Any ideas? 有任何想法吗?
You need to put all the special characters into character class. 您需要将所有特殊字符放入字符类。
[~!@#$^%&*\\(\\)_+={}\\[\\]|;:\"'<,>.?`/\\\\-]
If you want to add space also, then it should be 如果您还想添加空间,那么应该
[~!@#$^%&*\\(\\)_+={}\\[\\]|;:\"'<,>.?` /\\\\-]
