# Since JP.t already tests basic file IO, we will just focus on
# internal encode / decode test here. Unfortunately, to test
# against all the UniHan characters will take a huge disk space,
# not to mention the time it will take, and the fact that Perl
# did not bundle UniHan.txt anyway.

# So, here we just test a typical snippet spanning multiple Unicode
# blocks, and hope it can point out obvious errors.
