If it is set to "2000", the mapping falls back to the existing mapping based on the 2000 standard, otherwise, it defaults to 2022 mapping. Refer to the corresponding CSR for more detail.

Hello @naotoj .
Sorry for bothering you.

I have following question:
- Why GB18030.java.template is in src/jdk.charsets/share/classes/sun/nio/cs/ext/ directory even if the generated code is always stored into sun/nio/cs ?
I think the file should be moved to src/java.base/share/classes/sun/nio/cs and the file name should be GB18030.java instead of GB18030.java.template.
Is there specific reason ?
