Is the content of the file encoded in UTF-16 ?
How many lines does the file have ?

Comment 6 Dani Megert

I used a simple text file with 1 MB, no long lines, Cp1252 encoded. Everything fine. Then I switched the encoding and the workbench becomes unusable.

Right, my guess is that when you change to utf-16 all the lines delimiters are garbled turning the entire file in one huge line filled with invalid characters.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
