+## Restriction of Encode/Decode
+* Windows command prompt may not display characters correctly like "譁�蟄怜喧縺�".  
+  This is due to compatibility issues between Chinese & Japanese characters and the Windows command prompt.
+  * Chinese (Traditional/Simplified): Display wrong even if exporting with gbk or big5 encoding.
+  * Japanese: Display wrong even if exporting with sjis or euc-jp encoding.
+
+  In this case, display the data by specifying utf-8 encoding like below:
+  ```
+  cli-kintone --export -a <APP_ID> -d <FQDN> -e utf-8
+  ```
+  *This issue only occurs when displaying data on Windows command prompt. Data import/export with other means work fine with gbk, big5, sjis and euc-jp encoding.
