I'm using tcl 8.6.12

in tclsh:
set s \U5927\U4E1C\U5B9D\U9A6C
shows 4 generic characters

however in tkcon it displays properly
大东宝马

I'm not getting any errors.

hi,Dave B
Can tclsh call the same callstack？how to do it？The crash I test, without "大东宝马" is ok

You haven't shared your code, that crashed. It is therefore impossible
for anyone to reproduce the problem.

Create a short example code that crashes for you and show it here.

I found 8.6.12 this commit missing and we apply this to 8.6.12，the crash fixed
“大东宝马‘’ ´ó¶«±¦Âí] ´ó¶«±¦Âí has char in CP-1252

invalid UTF-8 characters

Same here, using tcl 8.6.9 on Linux - except that I get proper display
with tclsh too.

Using 8.6.12 I get the same characters on tclsh. I presume it depends on
the fonts available at the shell, not on TCL itself.
