Installation failure on Windows due to json gem native extension build error (Ruby 3.4,Ruby 3.3, no DevKit detected)

[InsPekToP]

I'm unable to install Jekyll on Windows due to a recurring failure when building the native extension for the json gem (version 2.18.0 is being pulled).
Environment:

OS: Windows 10/11 (x64)
Ruby version: 3.3.x (installed via RubyInstaller without DevKit / or with incomplete toolchain)
Ruby path: E:/Проги/Ruby/Ruby33-x64 (note: contains non-ASCII characters in user profile path C:\Users\МИХАИЛ)
Gem environment: RubyGems uses user install directory C:/Users/МИХАИЛ/.local/share/gem/ruby/3.3.0

Steps to reproduce:

gem install jekyll bundler
Or even gem install json --platform=ruby

Actual behavior:
Fails with:
The compiler failed to generate an executable file. (RuntimeError) You have to install development tools first.

checking for whether -std=c99 is accepted as CFLAGS... *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. ... mkmf.rb:480:in try_do': The compiler failed to generate an executable file. (RuntimeError)
You have to install development tools first.`

Also earlier attempts (with json 2.18.0) showed SIMD-related load errors due to кириллица (Cyrillic) in username path.
Expected behavior:
Jekyll installs successfully (or at least json gem installs in pure-ruby mode without requiring compilation).
Additional notes:

Windows is not officially supported by Jekyll (as per https://jekyllrb.com/docs/support/), but many users still use it.
Problem is very common on Windows when DevKit/MSYS2 is missing or incomplete.
Even --platform=ruby does not prevent json gem from trying to build native extension in recent versions.
Workarounds that help many people:
Install Ruby+DevKit from https://rubyinstaller.org/
Use WSL2 + Ubuntu
Force old json version: gem install json -v 2.6.3

Would it be possible to:

Make json gem more reliably fall back to pure-ruby mode on Windows when native build fails?
Or update documentation to strongly recommend Ruby+DevKit or WSL for Windows users?

Thanks for the great tool — Jekyll is awesome when it works!
