(Of course, with shitty filesystems, length of filenames could also be a problem. But let's not try to fix a problem that hasn't been reported yet.)

File naming: UCS-2 compatible option
====================================

Certain shitty filesystems do not allow characters beyond `U+FFFF` in filenames. For instance, FAT32 is such a filesystem that only allows UCS-2 characters. We need to offer a compatibility option to replace non-[BMP](https://en.wikipedia.org/wiki/Plane_(Unicode)#Basic_Multilingual_Plane) characters with `U+FFFD` REPLACEMENT CHARACTER, �. The option could be called `ucs2_compatible_filenames`.

I discovered this problem when backing everything up onto Baidu Cloud Drive.

Okay, looked at the code, found the bug:

https://github.com/Homebrew/brew/blob/59aac3347acf83e2b7950b8cb20df2b92986f4ec/Library/Homebrew/cli_parser.rb#L236-L238

Looks like `:env_var` should be `:env`.

Also commented on the original PR.

Well, just the same?

Haven't looked at the code.
