I have a requirement to parse the contents of a csv blob which has unicode characters. When I am trying to parse it using

Blob myBlob = EncodingUtil.base64Decode(response.getBody())

I am getting an exception saying -

"common.apex.runtime.impl.ExecutionException: Unrecognized base64 character: \u0003"

What would be the correct way to parse this blob ?

  • Is the response even encoded as base64? If it's not, you could simply .toString() the blob.

The getBody method returns the CSV data as a UTF-8 string. No additional parsing necessary.

String csvString = response.getBody();

If you wanted a blob, use getBodyAsBlob.

Blob csvBlob = response.getBodyAsBlob();

Regardless, if your file has non-UTF-8 characters, you won't be able to read it as UTF-8. You'll need to check the data you're receiving to make sure it's in the proper format.
