Not sure why. There are terminal emulators out there which support proportional fonts. Emacs is perhaps the only one whose terminal emulator currently supports bidi more or less in full, but is that related to proportional fonts? > What's the sledgehammer for Windows?

AFAIK wcwidth will give the results consistent with the UCD only if you use glibc. In Emacs, you have the functions char-width and string-width that take their data from EastAsianWidth.txt. Not sure about other facilities, and I don't really understand what environment are you asking about -- are you talking about C/C++ programs?
