Wrong characters from "tree" command

In textedit you may have to change the encoding under Options from "automatic" to utf-8 (or something else, I'm not sure what terminal does)

Textedit preferences let you set the default encoding for opening files if that helps.

Yes,

tree -n --charset=unicode > ~/Desktop/myapps.txt

does work, too!

Thanks!

From the man page for tree, it appears that the "ascii" charset is probably CP437, an ancient 8 bit encoding which does have those drawing characters. I'm not sure how TextEdit would automatically recognize that. "Unicode" is probably utf-16, which TextEdit should be able to recognize without any help.

This solved it (from https://apple.stackexchange.com/a/377260/112510 ):

Use command

tree -n --charset=ascii > ~/Desktop/myapps.txt

Fascinating. I think perhaps tree converts its own unicode to an ancient version of extended ascii which somehow textedit recognizes.

Does it work with -charset=unicode?

With a clean installation of Catalina 10.15.1, and never touching the TextEdit preferences, here is the result of:

tree -n --charset UTF-8 Downloads > tree.txt

Default macOS language is U.S. English. Default TextEdit font is Menlo Regular, and default encoding on plain text file opening is Automatic.

As noted before, you can't use "automatic", it has to be utf8

I'm still getting those weird characters such as │   ├──

Here's an analysis of what is happening: ├── is the utf-8 encoding for the drawing characters 251c 2500 2500 (e2 94 9c e2 94 80 e2 94 80) being read as if were in MacRoman encoding (which is presumably TextEdit's default).

I'm mystified by the error message you are getting.

You need to change "Plain Text File Encoding" to Unicode for opening.

Tom,

As far as I can tell, the tree --charset unicode, or --charset ascii equally produce ISO-8859-1 output encoding.

Interesting! That encoding doesn’t contain the drawing characters however.

Tom,

As far as I can tell, the tree --charset unicode, or --charset ascii equally produce ISO-8859-1 output encoding.
