Hi Jon, I figured there was one group that was doing a number of those, as many journals have the same sidebar with the same options and the same file naming conventions.
Re UTF-8, the worst offender was the American Geophysical Union who used a Western ISO formatting. It turns out that since very recently, Wiley is now handling this for them, and they are now using unicode.
I don't know if you recall, but I was setting up bookends server on a mac server for students to submit references for our group database. I had a php form that allowed the uploading of multiple ris files. So the students would just drop in all the ones they'd gathered, all at once. AGU's lack of unicode was a huge problem, essentially preventing batch uploading.

Now that link redirects to Wiley (instead of AGU's page). Prior to that, upon import of the ris file, all those accented characters in the title would be
mojibake'd, and all the symbols in the abstract (em dash, degree sign, etc., would be imported as html entities.
