Artist name display

I noticed today that three of my albums appear in the alphabetic pop-up as having non-English characters in the Artist Name. I burned them using dBpoweramp without any issues. Two of the albums feature violinist Cho-Liang Lin, and the third is a disc with Erich Kunzel and the Cincinnati Pops. I’ve read some threads about Roon allowing me to use my own metadata down the road, and this seems like the ideal case for it.
