## 字符集

IoTDB 包含多种字符集支持，默认使用 UTF-8 编码，并可以通过配置参数进行切换。

字符集相关的配置参数位于位于 `sbin` 目录下。
* `start-confignode.sh`：confignode 的配置文件，可以配置 ConfigNode 的字符集编码方式。
* `start-datanode.sh`：datanode 的配置文件，可以配置 DataNode 的字符集编码方式。

### 配置项

* -Dsun.jnu.encoding

|名字| -Dsun.jnu.encoding |
|:---:|:-----------------------|
|描述| IoTDB 所在操作系统编码方式 |
|类型| String |
|默认值| UTF-8 |
|改后生效方式| 重启服务生效 |

* -Dfile.encoding

|名字| -Dfile.encoding |
|:---:|:-----------------|
|描述| IoTDB 启动时的文件编码方式 |
|类型| String |
|默认值| UTF-8 |
|改后生效方式| 重启服务生效 |

### 配置项修改方式

在 `start-confignode.sh` 和 `start-datanode.sh` 文件中，修改 `iotdb_parms` 中的上述两个配置项

```
iotdb_parms="-Dlogback.configurationFile=${IOTDB_LOG_CONFIG}"
iotdb_parms="$iotdb_parms -DIOTDB_HOME=${IOTDB_HOME}"
iotdb_parms="$iotdb_parms -DIOTDB_DATA_HOME=${IOTDB_DATA_HOME}"
iotdb_parms="$iotdb_parms -DTSFILE_HOME=${IOTDB_HOME}"
iotdb_parms="$iotdb_parms -DIOTDB_CONF=${IOTDB_CONF}"
iotdb_parms="$iotdb_parms -DTSFILE_CONF=${IOTDB_CONF}"
iotdb_parms="$iotdb_parms -Dname=iotdb\.IoTDB"
iotdb_parms="$iotdb_parms -DIOTDB_LOG_DIR=${IOTDB_LOG_DIR}"
iotdb_parms="$iotdb_parms -Dsun.jnu.encoding=UTF-8"
iotdb_parms="$iotdb_parms -Dfile.encoding=UTF-8"
```
