Q: why idna2003 and idna2008 are not compatible? Give an example in java
A: IDNA2003 and IDNA2008 are not compatible because they use different algorithms for encoding internationalized domain names (IDNs) into the ASCII-compatible format required by the domain name system (DNS).
So far, so good.
IDNA2003 uses a simpler, table-based algorithm, while IDNA2008 uses a more complex, context-sensitive algorithm that provides better handling of certain characters and character combinations.
Completely wrong. IDNA2008 uses tables and is not context-sensitive. You see the problem. R's, John
