I haven't even got auto-correct activated, but InDesign insists on converting the string 0/0 to %. How can I suppress this? I'm using German InDesign CS5.5.
Wouldn't say that is an autocorrect.
Sounds more like a "ligature" or Open Type feature.
Open the character panel
Window>Types and Tables>Character
And use the Submenu - top right
I think Eugene is probably correct any you have Fractions enabled in the Open Type features. This should only be activated for selected type that actually is a fraction.
Also be sure you are patched to 7.5.3. I recall there were some bugs in the original release in the German localization.
Wow! How could a normal mortal be expected to discover that? (esp. when the menus are in German). Thanks.
