[UI Text - Unity 5.0.2.f1] Line break when "ri" occur in the text field

Today I found this weird behaviour writing within the inspector or assigning dinamically via C# script strings that contain occurrences with r+i, so that I see on my game the text component as if I inserted there a newline, for example, having a string like [quote]
this is a string
[/quote] I will then find on video this result: [quote]
this is a str
ng
[/quote] where also the ‘i’ disappear.
Anyone else happen this crap or it is just me?

on a second check, looks like it is related with a TTF font I applied to that component. BTW it is named “essay normal” I did find somwhere a long while ago.
