ASCII Filter Missing? (LO 3.6)

Encoded Text Files that (when opening) prompted me to select the character set & default fonts (ASCII Filter Options) in L.O. 3.4x and 3.5x now (in 3.6.0) open immediately without allowing me to change the character set. Is this a bug or am I doing something wrong?

Are they opening properly in 3.6.0?

Perhaps LO got smarter about figuring out which character set to use. If you do run into an issue here, please file a bug about it!
