使用方法:
解壓縮後在有java的windows環境下執行run.bat
使用ctrl+x (剪下)、ctrl+c (複製)、ctrl+v (貼上)與上面的按鈕進行操作

之前在玩Jakarta Commons時
看到了一個還蠻有意思的class
就是org.apache.commons.lang.StringEscapeUtils
它可以幫你把一些特殊字元在各種不同的應用中進行跳脫
我也為這個有趣的class弄了一個對我而言還算方便(其實是簡陋)的GUI介面來使用
最近卻發現我使用它的機會還蠻大的
像是在blog上po程式碼的時候...
所以雖然程式很簡單我還是跟大家分享一下
歡迎大家為它弄出一個更好的介面或功能再分享回來 :)
