<b>Here my observations:</b>
(using version: [503a0ef555])

On cmd.exe, I type: chcp 65001 and I use lucida console font instead of the default Rasters font to be able to use utf-8 on console. in that mode, fossil status will print filename correctly on the console. But not the fossil add command: since it print on screen before the conversion to utf-8. (I believe).
