Unfortunately, those character functions were removed (PrE 11?) from the Titler.
One way around that would be to use Photoshop/Photoshop Elements, or Adobe Illustrator, to create those Titles, with full Text handling functions, the Save_As a PSD, or similar, and Import those into PrE. The downside is that they will be Images, and not PrE Titles, so need to be re-edited, if necessary, back in Ps, or AI.
For intricate Text, I will usually use AI, then Open, or Place the AI Image in Photoshop, to do the full Rasterization for use in Video.
Good luck, and I have not read any response from Adobe, on why those very useful Text handling functions were removed.
