Is this similar to https://golang.org/issue/3754 ?

Comment 3:

I think this is a specific case of issue #3754, yes.  But I think we've made matters
worse on tip than they were before.

Comment 4:

Can you explain the "worse" bit in details, please? Thank you.

Comment 5:

i can't think of a good solution to this problem.
this is a dup of 3754, i believe.
we've never supported non-ascii encoding with any C programs
in the toolchain and we rely on cmd/go to correctly handle file paths for
those part of the toolchain.

Comment 6:

Large part of this will just go away once we have linker written in Go. (I think rsc
said that).

Comment 7:

this problem will be fixed once the compiler and the linker are converted
to Go.
Hopefully it could happen before Go 1.4.

Comment 8:

Previously we did not rewrite the file name in this way.  So although
you couldn't use the go tool, you could use 8g/8l to build Go programs
using files with odd names.  Now that no longer works.

Comment 9:

When you say "rewrite", do you mean "translate '\\' to '/'" ? If so, we always did so.
And it was done in 8l, never was in "go command". You still don't need "go command" to
"translate '\\' to '/'" .

Comment 10:

OK, if we used to do that, then I am mistaken.  I didn't see it
anywhere in the old code.  Sorry for the noise.

Making a dup. Let me know, if I am wrong about that.
