Description

$ ./ruby -Ilib -e "p Encoding.find('filesystem')"
#<Encoding:UTF-8>
./ruby -Ilib -e "p 'あ'.encoding.ascii_compatible?"                        
true
$ ./ruby -Ilib -e "p File.expand_path('あ', '/')"
"/あ"

The above is ok but

$ ./ruby -Ilib -e "p File.expand_path('あ', '/'.force_encoding('US-ASCII'))"
-e:1:in `expand_path': incompatible character encodings: UTF-8 and US-ASCII (Encoding::CompatibilityError)
	from -e:1:in `<main>'

For me this is unexpected one.

Added by matz (Yukihiro Matsumoto) about 2 years ago

* file.c (file_expand_path): should not just copy the encoding from fname. [ruby-core:28635] * file.c (EXPAND_PATH_BUFFER): set filesystem_encoding, not usascii for path buffer.
