> * when could/would we drop the PS backend altogether?
In my humble opinion,
the PS backend is still needed for CJK character handling.
When you copy and paste text from a PDF generated by the cairo backend,
some CJK characters are garbled.
By the PS backend, no such garbling occurs.
Here's a sample.
```
\version "2.22.0"
\markup {
\override #'(font-name . "HaranoAjiMincho")
{ 初見はハ長調で高音の白玉があった } }
\markup {
\override #'(font-name . "HaranoAjiMincho")
\override #'(font-features . ("jp90"))
{ 辻井 逗子 飴玉 } }
```
