Solution

  • The \mathbb{I} is not a roman numeral II, it is a blackboard bold capital I. Use \mathrm{II} for upright roman numeral II (or if you really don't want any space between them \mathrm{I\!I}.

    You should get the same symbol in Jupyter, but it may be that there is a problem with the font.
