Accented characters not showing every time

We started to use Openfire and Spark not a long time ago, and we are overall happy with the results. We are experiencing, however an issue that was already pointed out by several of our users.

We use Spanish a lot in the office, and we found out that Spark does not handle accented characters consistenly (á, é, í, ó and ú). Testing, we realized that Spark does allow us to write these characters some times, but we have been unable so far to consistenly reproduce these ocasions. I was wondering if anyone else has seen this issue before, and managed to solve it.

Any feedback will be greatly appreciated!

Such issues are hard to investigate. It can be a Spark bug or maybe system configuration. Those machines has Spanish regional settings? Can you try with the latest 2.6.0 RC1 version of Spark?
