Windows 10's limited Unicode font support makes progress bars look strange

[FredMSloniker]

I'm using ia to download some files, and for large files especially I'm noticing a problem. The tail end of the progress bar is using Unicode block elements to show progress by eighths, but of the fixed-width fonts available on a standard Windows 10 install, only DejaVu Sans Mono and SimSun properly display them. As a result, when using (say) Consolas in the command line, the tail end of the progress bar only displays "▌" correctly; the others are only shown as the 'unsupported Unicode symbol' glyph.
Given this, and given that the default Windows command line font is Consolas, would it be possible to have the progress bar on Windows only advance by halves instead of eighths for improved compatibility? Or, at the very least, support it as a configuration setting or something? I recognize this is kind of a nitpicky request, but it's been bothering me for a while, and I don't like the look of DejaVu Sans Mono.
