Ability to Disable Unicode Output During Vite Build

[DCMattyG]

Hi all, it appears that during the build process Vite will emit Unicode characters, such as in the this example:

`${colors.green(`✓`)} ${transformedCount} modules transformed.`

Is it possible to suppress this as it's causing issues in Windows environments where the logged output is being redirected back from the build process, specifically when calling something like "az acr build" from within a PowerShell script.

Yes, we could instruct every single Windows user to modify their system locale, but it would seem much simpler to simply offer a build switch or mechanism to disable Unicode, which is entirely unnecessary (though does look pretty).

Any ideas are welcome, but ideally it would be nice to either simply remove the Unicode output altogether, or offer a way to omit it for build environments or other situations where Unicode output can cause issues.
