fix: JWT Token Json Parsing Error At using Korean, Turkish...else purpose 1. JWT use Base 64 URL encoding So, Before Base 64 Decoding URL-safe character(-, _) should change to (+, /) 2. Including korean JWT payload is Json string That encoding by UTF-8 So, ByteArray Decoded by Base64 should change to UTF-8 String 3. Finally payload is Json So, Parsing And return To JS Object

fix: JWT Token JSON Parsing Error with non-ASCII characters
Purpose:
JWT tokens use Base64 URL encoding. Therefore, before performing Base64 decoding, URL-safe characters ('-', '_') must be replaced with standard Base64 characters ('+', '/').
The JWT payload (which may include non-ASCII characters such as Korean or Turkish) is a JSON string encoded in UTF-8. Thus, the byte array obtained after Base64 decoding should be converted into a UTF-8 string.
Finally, parse the UTF-8 string as JSON and return the resulting JavaScript object.
