Windows 10: Need CP437 Monospace ttf font

For a legacy program I am using, I need a monospace TrueType font with codepage 437 (or 850). I would like a sans serif font if possible. Does anyone know of such a font (or how one could rearrange another font to CP437)?

Unicode .TTF Monospaced Fonts Don't render correctly on most Windows Textbox or Edit Control, Text Editors in Windows 10

Using this file: https://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt and these Unicode C0 Control Special characters = "". Monospace fonts used : DejaVu Sans Mono FreeMono Inconsolata Everson Mono Source Code Pro Fira Mono TerminalVector---Mostly
symbols monospaced Problem: If I used any Monospaced Fonts in the Notepad, Wordpad, or most Windows Edit Control (Text box) or Text Editors that use this control, Like MS Visual Studio. The fonts all seem and appear to change but the characters can't be represented
properly and a square box appears for many characters, the actual font barely changes in form specially for fonts that use symbols instead of characters. I believe the Native windows monospaced family of font like the Consolas and Courier New are being used
as legacy fall-back fonts inadvertently and not letting the actual fonts in-use function properly. I'm Using Windows 10 Version 10.0.14393 Exception: If I used 3rd party tools that have there own Text Editor component and there dedicated rendering engine for
text viewing all the fonts work properly in those dedicated separate tools but not for the Windows Edit Control dependant tools and GDI based Text rendering. For Example: Notepad++ or any scintilla based editor works and so does ErgoEmacs, web browsers like
Chrome, Firefox(an older version) and a Terminal emulation tool called Mintty, along with Putty all render the fonts properly. It also functions properly when a plain unicode font or a non-monospaced font is used. But the problem is specifically with monospace
fonts. I was able to reproduce the problem on a fresh reinstall of windows. Please let me know If you can help, Thanks

 

Authoring a Monospace Font

I think you can use Fony to convert .fon files to .ttf if that's of any help.

 

Can't install any new TTF fonts (and it's not because of the firewall)


For some reason, I can no longer install TTF fonts on my windows 10 PC. Here is a folder filled with web/ttf fonts that I am trying to work with.

Every time I click on a TTF font, a small window appears onscreen, but only for a moment before it vanishes. I gather this would normally be the progress-bar window. For whatever reason it is just 'skipping'. The fonts never show up in my list.

I am aware of font installation problems that are related to the windows firewall. However, the firewall has always been on. I've also done a few reboots. No dice. I would appreciate any guidance. Also, let me know if I can provide further data.

Many thanks,
Matt
