Hey, I just go with whatever romanization they put down officially.
How different the systems for romanization can be is pretty effed up, I'm sure you'd agree.
For example:
"Nakky" "Sakichy" "Yossy" "P-A-T-I" "BACooN"
However, I'm still not going to type Kumai's given name as "Yulina". That just don't sit well with me.
