------------------------------
Summary: Multilingual Decoded problem
Key: CALCITE-2704
URL: https://issues.apache.org/jira/browse/CALCITE-2704
Project: Calcite
Issue Type: Bug
Components: avatica
Affects Versions: avatica-1.12.0, avatica-1.11.0
Reporter: pufan
Fix For: avatica-1.13.0
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}
