Hi Alan, Thanks. I appreciate your response.
Yes, I think GB13080 must continue to be GB13080-2000 for now. I was initially hoping to add a new character set with the name GB13080-2005. But I guess your suggestion of internally mapping one of the two versions (2000 or 2005) to "GB13080", based on the value of a new System property, version 2000 being the default, could be a better approach.

If I read this correctly, then your proposal is for GB18030 to continue to be GB18030-2000 but you would introduce a new charset GB18030 map to GB18030-2005 for the new version. Are you also proposing a system property or some means to have GB18030 be GB18030-2005 until the time is right to make it the default? -Alan
