Sample document with few CJK Ext-B characters
While CJK Ext-B characters in the sample file crowd together, it works fine in 4.4.

For me, it overlaps a bit differently in 4.3.
In 5.2, I don't see the ext-b character at all.

LibreOffice 4.4.2 v.s 5.0.4
TDF#96457 seems more like a META bug. It states Writer doesn't handle CJK EXTB characters very well in general. Issues includes
a) pasted text not rendered as rectangle
b) inconsistent behavior after reopen (docx, doc ).
c) have problem exporting pdf
d) unable to handle 5-digit non-BMP unicode character in HTML file ( tdf#81129)
This issue focused on formatting, particular on overlapping issue. And I find there seems no such a problem in 4.4. Can we have a regression on this?
I'm not an expert on issue classification, but I felt it is more clear that this issue stay dedicated.
Formatting problem is more related to VCL, but there are some other things to do to solve tdf#96457. If user copy-paste text from a browser, tdf#81129 has to be fixed first. For plain text, user might expect that extb font been selected when pasting those characters in plain text format as MS WORD does though not stated explicitly.

printscreen from 5.2
when I open your file I see only 6 characters - is it correct? In your screenshot is more characters..
No. There are 10 characters.
First 6 use MingLiU font, the others use MingLiU-EXTB font.
apparently windows specific problem - i copied the mingliu*.ttc into ~/.fonts on Linux and the bugdoc looks fine on anything from 4.4 to master
Windows master does look broken, first 6 characters work but then 3 of the 4 last ones are rendered as empty boxes
this could probably benefit from some bibisecting...
this is not a dataLoss bug, just a rendering problem (platform-specific even)
This isn't reproducible in 22.214.171.124 ( Windows10, traditional Chinese)

I guess that this issue has been solved after reintroducing WinSimpleLayout in 5.1.
