Ok, so:
{{#82l#82r#96#BE#92#A9}}
Consists of the following tokens:
{{#82}} {{l}} {{#82}} {{r}} {{#96}} {{#BE}} {{#92}} {{#A9}}
The #xx are UTF-8 escapes, however, none of the byte sequences are valid UTF-8
byte sequences. So this name is invalid.
I've noticed that CJK PDFs, such as the one here, sometimes contain invalid
escape codes which are not UTF-8. I assume in this case the codes actually
correspond to "90ms-RKSJ-H", which uses the "Adobe-Japan1" encoding (aka
"Shift-JIS").
Are you seeing different behaviour on the trunk?
