In normal situation, we can use ";" to show the next answer if there is one.
But if I do this, it shows me

error: char_code/2: Cannot represent due to 'character_code'

In stead of ";", I use "shift + ;", and prolog gives me a prompt 

Unknown action: : (h for help)   Action?

then if I input ";", the designable answers will be shown one by one.

What is the problem?

Use swipl-win.exe instead of swipl.exe can solve this problem.(I tried 6.x and 7.x)

By the way, swipl works well under MacOS.
