更改ibus倉頡五代預設語系為繁體中文， （原本為簡體）

ibus有個問題，當它從環境變數判斷中文模式時，
如果沒有正確的值，會使用預設值，而預設值是簡體中文 （棍）

比方你想使用英文桌面搭配中文輸入法時就會遇到這個問題，
或是你的環境變數沒設好，也會遇到打不出倉頡的字或變亂碼

定義及要修改的地方在這裡
/usr/share/ibus-table/engine/table.py

裡面有註解， 0是簡中， 1是繁中，
        # self._chinese_mode: the candidate filter mode,
        #   0 is simplify Chinese
        #   1 is traditional Chinese
        #   2 is Big charset mode, but simplify Chinese first
        #   3 is Big charset mode, but traditional Chinese first
        #   4 is Big charset mode.
        # we use LC_CTYPE or LANG to determine which one to use

line 124:  可以搜尋if IME declare as Chinese IME找到那段code

                if self.db._is_chinese:
                    # if IME declare as Chinese IME
                    return 1
                else:
                    return -1

把原本的0改成1, 再把 ibus-daemon kill重啟 就OK囉～ 
# sudo pkill ibus-daemon && ibus-daemon -d

MySQL 設定為 utf8

設定 /etc/mysql/my.cnf

１。　在[client]區加入
default-character-set = utf8

2. 在 [mysqld]

character_set_server=utf8
collation_server=utf8_unicode_ci

3.存檔後重啟mysql

sudo service mysql restart

4.　檢查mysql是否變更為utf8

mysql -uroot -p

輸入mysql root密碼後登入mysql

mysql>

mysql> SHOW VARIABLES LIKE 'character_set_%';
