Regex pattern in java

What would be a regex pattern for the following ' and ® in Java. I have tried the following but have not been successful

1. &#[0-1][0-1][0-1]开发者_开发技巧
2. &#\d\d

Ok, then it should be:

str.matches(".*&#\\d{1,3};.*"); 

This matches &# followed by 1, 2 or 3 digits and then a ;)

These should work:

1. ".*\\x27.*" matches an embedded apostrophe
2. ".*\\xae.*" matches an embedded registered trademark symbol

I tested with String.match

If you need longer unicode values you can use

1. ".*\\u0027.*" matches an embedded apostrophe
2. ".*\\u00ae.*" matches an embedded registered trademark symbol
