Re: [icu-support] [icu_support]how to customize the data for icu4j?

[George R. <gr...@us...>]

Since there is no data item called ucdata, I presume you're talking about=20
ucadata.  It should be noted that using data from one version of ICU in=20
another version of ICU (both ICU4C and ICU4J) may not work very well.   If =

you really want to use data from a specific version of ICU, it's just=20
better to use that version of ICU.  It's not uncommon for the data to=20
change with a lock in step change in the code.

If you decide to ignore my advice, you should at least run the tests with=20
the new data.

Hi Mark,
Thanks for your remindering. Actually, I just want to replace the
ucdata in 3.4 with that in 3.2 :)
