Subject: [ruby-core:115376] [Ruby master Bug#9189] Build failure on Windows in case of nonascii TEMP environment.

Issue #9189 has been updated by pcai (Peter Cai).





I'm unable to reproduce. Windows presents an ascii-safe alias of the TEMP folder for me so I can't seem to test the handling:



* windows 11 (Version 10.0.22621 Build 22621)

* Ruby+Devkit 3.2.2-1 (x64)



```

C:\work>ruby -e "system('set TEMP')"

TEMP=C:\Users\6863~1\tmp



C:\work>set TEMP

TEMP=C:\Users\6863~1\tmp



C:\work>cd C:\Users\������\tmp



C:\Users\������\tmp>echo %cd%

C:\Users\������\tmp



C:\Users\������\tmp>ruby -v

ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x64-mingw-ucrt]

```

----------------------------------------

I experienced a build failure during build extension library with trunk on Windows.

I found the cause of this error is mkmk failure.

Here is a part of mkmf.log

	Cannot create temporary file in C:\Users\??���?AppData\Local\Temp\: Invalid argument





The TEMP environment varable is

	

	C:\work\ruby-2.1.0-r43936>set TEMP

	TEMP=C:\Users\������\AppData\Local\Temp



It seems that miniruby cannot handle encoding properly.

	

	C:\work\ruby-2.1.0-r43936>miniruby -ve "p ENV['TEMP']"

	ruby 2.1.0dev (2013-11-30 trunk 43936) [i386-mingw32]

	"C:\\Users\\\xED\x9D\xAC\xEC\x84\xAD\\AppData\\Local\\Temp"



	C:\work\ruby-2.1.0-r43936>miniruby.exe -ve "p ENV['TEMP'].encoding"

	ruby 2.1.0dev (2013-11-30 trunk 43936) [i386-mingw32]

	#<Encoding:ASCII-8BIT>	

	

Whereas, the final ruby can handle encoding properly.



	C:\work>ruby -ve "p ENV['TEMP']"

	ruby 2.1.0dev (2013-11-30 trunk 43923) [i386-mingw32]

	"C:\\Users\\������\\AppData\\Local\\Temp"	



	C:\work>ruby -ve "p ENV['TEMP'].encoding"

	ruby 2.1.0dev (2013-11-30 trunk 43923) [i386-mingw32]

	#<Encoding:CP949>
