| Rule of this file: |
|
53
|
|
|
| 1. key should always be in lower case ascii so we can do case insensitive |
|
54
|
|
|
| comparison in the code faster. |
|
55
|
|
|
| 2. value should be the one used in unicode converter |
|
56
|
|
|
| |
|
57
|
|
|
| 3. If the charset is not used for document charset, but font charset |
|
58
|
|
|
| (e.g. XLFD charset- such as JIS x0201, JIS x0208), don't put here |
