Hello,
I don't know why, but here the file opened fine (but all text was in just three lines).
Is this the lyric
http://www.jpopasia.com/lyrics/22442/sid/uso.html ?
Copy&Paste worked fine here for the tree lyrics above. Maybe the problem is in the text-box (I used a third-party component for that, so I really doesn't know if there is any possible problem in there).
So what can be done?
1 - Copy & Paste the lyric over a new Notepad window
2 - Click at 'Save As', and select 'Unicode' as Encoding
3 - Save the file as the same name of the music file, example, if the song is 'Sid - Uso.mp3', save as 'Sid - Uso.lrk' (note that is '.lrk' and not '.lrk.txt')
4 - Play the song.
I'm having many problemas at Unicode, is because Lyrik was programmed in VB6 and there are no Unicode support, so I had to do my tricks

I'm planning to rewrite/remake Lyrik in C#, but until 2010 I have a lot of work to do (undergratuating & stuff)
