Oh, good point, i overlooked that in your posting, sorry.

The mandoc(1) utility does support the roff(7) .ds request.

Given the test file appended at the end of this posting,
i get the following output:

$ /usr/local/bin/nroff -c -mandoc -Tascii char.in > char.out_ascii
char.in:10: name expected (got a special character)
char.in:13: empty escape name

$ mandoc -Tlint char.in 
char.in:10:5: ERROR: escaped character not allowed in a name
char.in:13:5: ERROR: escaped character not allowed in a name

The "test text" is formatted in bold by groff,
but in normal roman font by mandoc.

Thus, mandoc(1) completely ignores a .ds request
if the name contains an escape sequence,
which is the behaviour that you considered as desirable
for groff as well.
It does not insert the definition into the token stream.

Well, even if people rarely run into the problem, if there is an
easy way to improve groff's behaviour, it should probably be done.

$ cat char.in

.Os OpenBSD
.Nm ds-char
.Nd character handling by the define string request
This is a broken bar: \(bb
.ds \(bb \fBx
test text \fR after define string with \e(bb
.ds \[] \fBx
test text \fR after define string with \e[]
