Unable to decode base64 string in java

Question

I am trying to decode base64 string. But somehow it is not decoding complete string. Below is base64 string.

I can decode this base64 string https://www.base64decode.org/ and it decodes it correctly. But when I tried to decode it using code then it break in between.(I am not sure bur because of some special character.) Below is the code which I am using to decode.

StringUtils.newStringIso8859_1(Base64.decodeBase64(labelResponse.getLabelUrl().getBytes()))

I don't know what is going wrong.

Output which I am expecting.

Answer 1

It should be problem with default charset on your system. Try this,

StringUtils.newStringIso8859_1(Base64.decodeBase64(str.getBytes(StandardCharsets.UTF_8)))

Your JVMs default charset should be other than UTF-8. In the above code UTF-8 Charset is passes

Answer 2

Can you specify how do you obtain the image? If it is from a server that you control, or from an artifact that returns the image, you must be sure that there are not special character in the base64 image string. You can do that using for example, the Javascript function encodeURIComponent(). If you are working with Java you can check this link to see its equivalent Java equivalent to JavaScript's encodeURIComponent that produces identical output?
