Java encoding : UTF-8, Big5, x-MS950-HKSCS
Suppose you got a file in Big5 containing some HKSCS characters (e.g. 深水埗, 赤鱲角, etc). When your environment (Ref: Charset.defaultCharset( ) ) is either UTF-8 / Big5, you will never get the things work. The proper encoding should be "x-MS950-HKSCS" This situation happens when I'm try the same pieces of code in Java console / Eclipse console and JSP @ Tomcat. While JSP works fine, but sucks in console mode. Finally I found the JSP is actually using encoding "x-MS950-HKSCS". To set environment charset in Eclipse: Right click on the file that you are going to execute (e.g. Testing.java), then "Properties" → "Run/Debug Settings" → "Common" → "Encoding". Type "x-MS950-HKSCS" in the field. What a pity!
