All inclusive Charset to avoid “java.nio.charset.MalformedInputException: Input length = 1”?

Question

I\'m creating a simple wordcount program in Java that reads through a directory\'s text-based files.

However, I keep on getting the error:

java.nio.c         


        

Answer 1

Creating BufferedReader from Files.newBufferedReader

Files.newBufferedReader(Paths.get("a.txt"), StandardCharsets.UTF_8);

when running the application it may throw the following exception:

java.nio.charset.MalformedInputException: Input length = 1

But

new BufferedReader(new InputStreamReader(new FileInputStream("a.txt"),"utf-8"));

works well.

The different is that, the former uses CharsetDecoder default action.

The default action for malformed-input and unmappable-character errors is to report them.

while the latter uses the REPLACE action.

cs.newDecoder().onMalformedInput(CodingErrorAction.REPLACE).onUnmappableCharacter(CodingErrorAction.REPLACE)
