How to ensure that Java programs use UTF-8 encoding

I recently found that relying on the JVM's default encoding can lead to errors I should explicitly use specific encoding ex. use UTF-8 when using string, inputstreams, etc

Thank you, nayn

Solution

It's not a direct answer, but in order to simplify the work, I'm glad to know that in a good ide, you can only search the used inputstreamreader, outputstreamwriter, string #getbytes(), string (byte []), properties #load(), urlencoder #coding(), urldecoder #decode() and consorts. You can pass charset and update it accordingly You also want to search FileReader and filewriter and replace them with the first two mentioned classes Yes, it's a tedious job, but it's worth trying. I prefer to rely on environmental details

For example, in eclipse, select the item of interest, press Ctrl h, switch to the Java Search tab, enter, for example, inputstreamreader, check the search for option constructor, select sources as the only search in option, and then execute the search
