Mixing
Character Convert Regex in Java
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am trying to make a text converter for file names with regex, in this text there are some different dash types and hyphen types minus signs etc.etc. I want to convert them all to just a simple hyphen.
there are several types of different dashes and their unicodes are here:
u2212 u002D u05BE u2011 u2012 u2013 u2014 u2015 u207B u208B u2212 uFE58 uFE63 uFF0D
if a character is one of these unicodes, then I want to convert it to simple hyphen which is u2010 with regex.
How can make this character convert regex with java ?
At first I was checking the file name is valid or not like this:
private static final Pattern FILE_NAME = Pattern.compile("^[a-zA-Z0-9_\u2212\u002D\u00AD\u05BE\u2010\u2011\u2012\u2013\u2014\u2015\u207B\u208B\u2212\uFE58\uFE63\uFF0D\.\s\,\[\]()\{\}]+$");
if (!FILE_NAME.matcher(file.getFilename()).matches()) {
throw new FileValidationException(FILE_NAME_INVALID);
}
but now I don't want to validate it I just want to replace characters with hyphen u2010

It should look like:
name = name.replaceAll("[u2212u002Du00ADu05BE"
+ "u2011u2012u2013u2014u2015u207Bu208Bu2212uFE58uFE63uFF0D]", "u2010");
Here u2212 are in java chars with the 4-digit hexadecimal values of UTF-16.
There is no magic, u0063 is the same as c like in public u0063lass X { }.
Resource for dash like Unicode.

Use <TargetString>.replaceAll(<pattern>, <replacement>) (See: Java 8 API: String)
In your case this would be: file.getFilename().replaceAll(FILE_NAME.toString(), "u2010")

You can do it like this:
fileName.replaceAll("u2212|u002D|u05BE|u2011|u2012|u2013|u2014|u2015|u207B|u208B|u2212|uFE58|uFE63|uFF0D", "u2010");
