1. There is nothing that I am doing as far as I know that limits the use of Unicode characters with the "run file" parameters. But the underlying Mozilla code that I am using I believe does limit this. Given that, there is no easy way to support unicode with this function.

2. When you say "wait until the program launched has finished" I am not sure what you mean. What is it that you want to stop and wait until the execution file is finished?

Normally in filters, it is quite common for the filter action to initiate an async operation that must be sequenced (that is, each step must wait until the previous has completed.) A move is the obvious example. But in those cases, the filter itself does not wait. If that is what you need, then that can be implemented with a javascript listener that manages the state and process. But I don't see how to design that into the simple filter action itself, as I would not know what the sequence of operations is that you need.

A good example of where I might use that is in print followed by move. Currently, print does not play well with moves, because they are both competing for access to the message. What I could do is to first do the print, then when it is completed schedule the move. But there is no way to manage that sort of multi step operation from the filter editor menus, only by writing custom javascript to do the particular sequence that you want.

So in short, I don't know of a straightforward, general way to do what you are asking.

2. Assuming that your text to speech program has some method to denote when it is done, it would not take much to create a queue of messages to be read aloud. I just think that it is beyond the reasonable capability of a custom message filter, and more in the line of what would be done in an extension.
