I have the WP8 with Portico on Lumia 920 but the bug already existed before that. I can't for some reason, add the word "anh" into the custom dictionary. WP8 continues to add the red squiggle under it even though I have added to the dictionary at least ten times. The interesting part is that every single other words that I have added worked fine.
Can someone try adding the word "anh" into the custom dictionary? Does it work for you?
