在開始用unicode之前是不能開啟任何資料庫的，否則Stata會提醒你data in memory would be lost 還有there must be no data in memory]

cd "D:\long term care\CHARLS\stata\data\household_and_community_questionnaire_data" 【先設定你的working directory】

unicode analyze psu.dta

(Directory ./bak.stunicode created; please do not delete)

File summary (before starting):

1 file(s) specified

1 file(s) to be examined ...

File psu.dta (Stata dataset)

2 str# variables need translation

----------------------------------------------------------------------------------------------------------

File needs translation. Use unicode translate on this file.

File psu.dta needs translation

File summary:

1 file(s) need translation

【總結：Stata告訴你，你這個file需要轉換】

【這裡就是讓Stata把資料轉換為支援中文的UTF-8，轉換完畢後，檢查資料，中文終於不是亂碼了，大功告成！】

一般是編碼不一致造成的亂碼。用高版本stata14試試。如果還是不行可以轉碼。命令如下：unicodeencodingsetgb18030unicodeanalyze*unicodetranslate*,invalid如果不行就還原：unicoderestore*
