Build utf.d with MS-COFF failed

[Pierre via Digitalmars-d-learn]

Hello, I can't build my project with MS-COFF option.

I'm using DMD 2.069.

I got this error :
utf.d(1109) : invalid UTF-8 sequence (at index 1)

I used these options with visual D:
Compiler       : DMD
D-Version      : D2
Output Type    : DLL
Subsystem      : Not set

Compilation    : Combined compile and link

Thank you for your help.
