Lucas,
Have you tried the "Check Unicode Validity" under the Checks menu in Toolbox? It will check the whole file. Sometimes the trouble spot is a bit beyond the point where the printing stops.
If that doesn't give you any useful results, then send me your project (data, and all the *.prj, *.typ, *.lng files), and I'll see if I can find anything strange. Send it to Toolbox @
sil.org (without the spaces).
Or, if you prefer, contact me on Skype and we can discuss using TeamViewer, which would let me see your computer. I'm Skype ID: KB9876
(For what it's worth, the classic approach to solving such a problem is to trim the data. What happens if you only have the plain i and u and the î and û as the data? What happens if you chop the file off after the first 10 entries after the printing ends? By eliminating the OK data, this type of process should eventually narrow the problem down to a single entry.)
