/*
cycheng@ca.ibm.c... we got inconsistent results when using the UTF-16BE iterator and the UTF-8 iterator.
weiv    ucol_strcollIter?
cycheng@ca.ibm.c... e.g. s1 = 0xfffc0062, and s2 = d8000021
weiv    these are the input strings?
cycheng@ca.ibm.c... yes, using the utf-16 iterator and UCA with normalization on, we have s1 > s2
weiv    will check - could be a problem with utf-8 iterator
cycheng@ca.ibm.c... but if we use the utf-8 iterator, i.e. s1 = efbfbc62 and s2 = eda08021, we have s1 < s2
weiv    hmmm
cycheng@ca.ibm.c... note that we have a standalone high surrogate
weiv    that doesn't sound right
cycheng@ca.ibm.c... we got the same inconsistent results on AIX and Win2000
weiv    so you have two strings, you convert them to utf-8 and to utf-16BE
cycheng@ca.ibm.c... yes
weiv    and then do the comparison
cycheng@ca.ibm.c... in one case, the input strings are in utf8, and in the other case the input strings are in utf-16be
weiv    utf-16 strings look like a little endian ones in the example you sent me
weiv    It could be a bug - let me try to test it out
cycheng@ca.ibm.c... ok
cycheng@ca.ibm.c... we can wait till the conf. call
cycheng@ca.ibm.c... next weke
weiv    that would be great
weiv    hmmm
weiv    I might be wrong
weiv    let me play with it some more
cycheng@ca.ibm.c... ok
cycheng@ca.ibm.c... also please check s3 = 0x0e3a0062  and s4 = 0x0e400021. both are in utf-16be
cycheng@ca.ibm.c... seems with icu 2.2 we have s3 > s4, but not in icu 2.4 that's built for db2
cycheng@ca.ibm.c... also s1 & s2 that I sent you earlier are also in utf-16be
weiv    ok
cycheng@ca.ibm.c... i ask sherman to send you more inconsistent data
weiv    thanks
cycheng@ca.ibm.c... the 4 strings we sent are just samples
