用Unicode转换字符串以在Java中显示unicode？

Question

I am trying to convert strings that contain a unicode to the actual character but everything I have found so far either only work if the string is only the unicode or converts the symbol to the code.

This is the string I am using as an example right now

Rebroadcast of Shows from the past Week! RPGs, Talk shows, Science, Wisdom, Vampires and more - Good stuff! \\u003c3 - !rbschedule for more info

I am getting this in from an API call so I can't just write it as \\ instead of the \\\\.

Answer 1

如果将所有“ //”动态替换为“ /”怎么办？

Answer 2

\\

That is called escaping , and it is what is currently blocking you from seeing the < character.
Un-escaping is not what you'd actually want to do manually , as there are many caveats.

You might want to use Apache common-text StringEscapeUtils#unescapeJava

final String result = StringEscapeUtils.unescapeJava(yourString);

That will output "...Good stuff! <3 - !rbschedule for more info..."

The Maven dependency

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-text</artifactId>
    <version>1.6</version>
</dependency>

Or for Gradle

compile group: 'org.apache.commons', name: 'commons-text', version: '1.6'
