An Enhanced Edition user with Polish language encountered a crash caused by this mod. http://gibberlings3.net/forums/index.php?showtopic=28161&page=49#entry249321
I believe the cause of the crash is that the text installed by this mod is ANSI encoded, whereas EE games that aren't using English language require text to be encoded as UTF-8.
I have added a patch
for Reunion to the BiG World Fixpack that uses HANDLE_CHARSETS to convert the ANSI-encoded tra files only when EE game type is detected.
Since my patch is part of the Fixpack, I referenced the copy of iconv that we include with the Fixpack; if you follow my approach and add HANDLE_CHARSETS in the next release, remember that you will need to include a standalone copy of iconv in the mod package. I would recommend keeping the tra files in non-UTF8 encoding in the mod package and using the HANDLE_CHARSETS conversion at install-time so you will still have a single mod package for both EE and non-EE games.
The Big World Fixpack also includes a couple of other patches
for your mod to make it compatible with EET.
