啟動PL/SQL Developer 報字元編碼不一致錯誤,Database character set

Database character set (AL32UTF8) and Client character set (ZHS16GBK) are different.
Character set conversion may cause unexpected results.

Note: you can set the client character set through the NLS_LANG environment variable or the NLS_LANG registry key in
HKEY_LOCAL_MACHINESOFTWAREORACLEKEY_Oracle_10g.

開啟登錄檔,透過命令regedit。找到到文中提示的路徑，發現NLS_LANG鍵的值為:

SIMPLIFIED CHINESE_CHINA.ZHS16GBK

修改為：SIMPLIFIED CHINESE_CHINA.AL32UTF8即可
