Research direction

Start by locating Base64Variant.decodeBase64Byte() and inspect how a non-ASCII character becomes the byte used for lookup. Reproduce the issue with a non-ASCII input, then verify the method returns BASE64_VALUE_INVALID instead of throwing ArrayIndexOutOfBoundsException.

Written by the indexing model from the issue text.

Description

The current implementation wrongly assumes byte to be an unsigned data type and crashes with ArrayIndexOutOfBoundsException.
