Hi, Vladimir:
Maybe my question is a little picky.:)
I noticed that the data for getCharsetsInfo of our charsetprovider
implementation is hardcoded. So is it possible to provide a more flexible
approach?
ResourceBundle is an option, but it has some problem in bootstrap.
Once I am trying ICU4J as default charset provider on Harmony, there will be
a bootstrap problem, since when loading required data for charset by
resourcebundle, the ClassLoader.loadResourceBundle still needs
charset. Then an initilization error will thrown.
I have thought of two possible approach:
(1) Load the charset information by native code in initialization.
(2) Using a bootstrap charset, for example, ISO-8859-1, to load data
for other charset.
I guess, maybe it deserves to discuss a little about the approach(2) .
It will be a great convenience for our customer if they are permitted to
choose charset provider. But some of them are not designed for class
library, that is, they will have bootstrap problem.

Attached test bundle, instruction and patch for current code combined
new implementation with ICU. So, I have the same 228 charsets
available - about 90 charsets used from the new bundle, and not
implemented charsets used from ICU.
The full list of charsets supported with the current bundle + ICU:
