            Bug ID: 29049
           Summary: [gdb, check-read1] FAIL: gdb.rust/unicode.exp: print D
                    in string
           Product: gdb
           Version: HEAD
            Status: NEW

  Target Milestone: ---

With make check I get:
...
(gdb) PASS: gdb.rust/unicode.exp: print D
print "𝕯"^M
$2 = "𝕯"^M
(gdb) PASS: gdb.rust/unicode.exp: print D in string
...
but with check-read1 I get instead:
...
(gdb) PASS: gdb.rust/unicode.exp: print D
print "\355\240\265\235\225¯"^M
$2 = "\355\240\265\235\225¯"^M
(gdb) FAIL: gdb.rust/unicode.exp: print D in string

I don't really have a theory about this one.
I don't see why read1 would affect this.

I've tried this to see if this was related to reading in the .exp file:
...

but that didn't help.
