|

| Rule of this file:
|
||||
| 1. key should always be in lower case ascii so we can do case insensitive
|
||||
| comparison in the code faster.
|
||||
| 2. value should be the one used in unicode converter
|
||||
|
|
||||
| 3. If the charset is not used for document charset, but font charset
|
||||
| (e.g. XLFD charset- such as JIS x0201, JIS x0208), don't put here
