+# gns_i18n高级包
+
+## 可获得性
+
+本特性自openGauss 7.0.0版本开始引入
+
+## 特性简介
+
+gms_i18n高级包主要实现国际化功能。在安装完数据库后，直接通过插件加载方式创建。
+
+## 客户价值
+

+
+## 创建Extension<a name="section21088306113"></a>
+
+创建gms_i18n Extension可直接使用CREATE Extension命令进行创建：
+
+```
+openGauss=# CREATE Extension gms_i18n;
+```
+
+## 使用Extension<a name="section107391050141118"></a>
+
+### 函数声明
+- RAW_TO_CHAR(data IN RAW, src_charset IN VARCHAR2 DEFAULT NULL)
+  描述：将RAW数据从有效的字符集转换为数据库字符集中的VARCHAR字符串。
+  参数详解：data：raw类型数据，src_charset：源字符集。
+- GMS_I18N.STRING_TO_RAW(IN strdata varchar2, IN dst_chrset varchar2 DEFAULT NULL)
+  描述：将VARCHAR字符串转换为另一个有效的字符集，并将结果作为原始数据返回分。
+  参数详解：strdata：需要转换的字符串；dst_chrset：目标字符集。
+
+### 函数使用
+raw_to_char函数
+```sql
+openGauss=# select gms_i18n.raw_to_char(hextoraw('616263646566C2AA'), 'utf8');
+ raw_to_char 
+-------------
+ abcdefª
+(1 row)
+
+```
+
+strin_to_raw函数
+```sql
+openGauss=# select gms_i18n.string_to_raw('abcdefª', 'utf8');
+  string_to_raw   
+------------------

+## 删除Extension<a name="section1587441381220"></a>
+
+在openGauss中删除gms_i18n Extension的方法如下所示：
+
+```
+openGauss=# DROP Extension gms_i18n [CASCADE];
+```
+
+>![](public_sys-resources/icon-note.png) **说明：** 
+>
+>如果Extension被其它对象依赖，需要加入CASCADE（级联）关键字，删除所有依赖对象。
