> When we execute SQL with Chinese characters, we find that the server parses it in gibberish.
> After checking the code, we found that:
> org.apache.calcite.avatica.server.AvaticaJsonHandler.java line 109：
> {code:java}
> //The readFully method USES utf-8 encoding internally.
> rawRequest = AvaticaUtils.readFully(inputStream, buffer);
> {code}
> But in the org.apache.calcite.avatica.server.AvaticaJsonHandler.java line 116：
> {code:java}
> // Decoded using iso-8859-1 Cause Chinese garble.
> final String jsonRequest = new String(rawRequest.getBytes("ISO-8859-1"), "UTF-8");
> {code}
