--- Comment #2 from V Stuart Foote <vstuart.foote at utsa.edu> ---
@Aron,

Your screen clip shows issues both with line formatting--but more so with font
fallback--which seems the issue here and makes sense as Liberation Mono has
limited coverage of CJK. And, font fallback got major rework 5.2 -> 5.3 with
implementation of more DirectWrite use with HarfBuzz.

Believe the "Text" import defaults to using the "Preformatted Text" style form
default template and is assigned Liberation Mono.

When I open this, if I choose the GB-18030 encoding and a CJK friendly font
other than Liberation Mono--which has limited coverage of the glyphs needed for
correct layout--e.g. NSimSun, no issues with fallback or line formatting.

On import believe empty paragraphs/crlf--those with no GB-10830 glyphs--are
picked up in the UI local as set.  So in an en-US local, I get a mix of Asian -
Chinese (simplified) paragraphs and Western - Default English (USA).

IMHO this seems correct, but a CJK user would need to confirm the system local
is picked up as the Default for empty paragraphs.

Perhaps retest and adjust the font for the import?
