ATK is not recognising ½ even after including in sk,lk and grammer.
Thank you for contacting us.
This is indeed a limitation of our TEXT offer (not only in the ATK but also in the low level SDK).
In which context do you need it? If in a math context, maybe you could use the MathWidget?
If in a text context, we have no alternative to offer.
Does it support Roman Numerals?
currently, as the roman characters are basic letters, these are normally recognized. The problem is that as our resources do not support Roman numbers by themselves, it is not likely the accuracy will be good. We then recommend you create your own resource (ideally ludef) to have a better accuracy: https://developer-support.myscript.com/support/discussions/topics/16000007921.
