Thank you for your input Nathan.

My version of nroff is as follows:

 $ /usr/bin/nroff --version
GNU nroff (groff) version 1.19.2

The MD5 checksum of eqn.1 is as follows:

 $ md5 eqn.1
MD5 (eqn.1) = b9357013cc6e126c788b9fa281f06fa4

As far as I know there have been no changes in the ko-man port:

https://svnweb.freebsd.org/ports/head/korean/man-doc/

To confirm this, I've just downloaded ko-man using pkg, and I copied the
eqn.1.gz from /usr/local/share/man/ko/man1/eqn.1.gz and checked its md5
checksum:

 $ md5 eqn.1
MD5 (eqn.1) = b9357013cc6e126c788b9fa281f06fa4

This appears to be exactly the same file. Running the above nroff on the file
gives this output:

 $ /usr/bin/nroff -man eqn.1 > /dev/null
eqn.1:20: a space character is not allowed in an escape name
eqn.1:20: a space character is not allowed in an escape name
eqn.1:35: a space character is not allowed in an escape name
eqn.1:35: warning: numeric expression expected (got `j')
eqn.1:37: a space character is not allowed in an escape name
eqn.1:37: warning: numeric expression expected (got `i')
eqn.1:45: a space character is not allowed in an escape name
eqn.1:46: a space character is not allowed in an escape name
eqn.1:47: a space character is not allowed in an escape name
eqn.1:48: a space character is not allowed in an escape name
eqn.1:49: a space character is not allowed in an escape name
eqn.1:50: a space character is not allowed in an escape name
eqn.1:51: a space character is not allowed in an escape name
eqn.1:52: a space character is not allowed in an escape name
eqn.1:186: a space character is not allowed in an escape name
grotty:<standard input>:10935: character above first line discarded
eqn.1:847: a space character is not allowed in an escape name

I also seem to have another nroff in /usr/local/bin/nroff. I tried with that:

$ /usr/local/bin/nroff --version
GNU nroff (groff) version 1.18.1
$ /usr/local/bin/nroff -man eqn.1 > /dev/null
eqn.1:20: a space character is not allowed in an escape name
eqn.1:20: a space character is not allowed in an escape name
eqn.1:35: a space character is not allowed in an escape name
eqn.1:35: warning: numeric expression expected (got `j')
eqn.1:37: a space character is not allowed in an escape name
eqn.1:37: warning: numeric expression expected (got `i')
eqn.1:45: a space character is not allowed in an escape name
eqn.1:46: a space character is not allowed in an escape name
eqn.1:47: a space character is not allowed in an escape name
eqn.1:48: a space character is not allowed in an escape name
eqn.1:49: a space character is not allowed in an escape name
eqn.1:50: a space character is not allowed in an escape name
eqn.1:51: a space character is not allowed in an escape name
eqn.1:52: a space character is not allowed in an escape name
eqn.1:163: name expected (got a magic token): treated as missing
eqn.1:186: a space character is not allowed in an escape name
eqn.1:847: a space character is not allowed in an escape name

The results seem nearly the same.

Can you confirm the version of nroff you are using and the md5 checksum of the
file eqn.1 are the same as mine?
