控制字符, col 就可以移除掉，我不知道对不对网上看来的，有其它好方法求赐教，比如man find >m-find.txt或者 `tree -L 1 >tree-1.txt - col 这个命令的源码在哪？如何找到最新版？
NAME
col -- filter reverse line feeds from input
SYNOPSIS
col [-bfhpx] [-l num]
DESCRIPTION
The col utility filters out reverse (and half reverse) line feeds so that the output is in the correct order with only forward and half forward line feeds, and replaces white-space characters with tabs where possible. This can be useful in processing the output of nroff(1) and tbl(1).
HISTORY
A col command appeared in Version 6 AT&T UNIX.

- 似乎是中文引起的错误
- 另外找了几个，虽然不报错，但也不支持中文
- https://github.com/karelzak/util-linux
- linux的， macos 上编译困难
- https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/tree/Documentation/deprecated.txt

Supplement 2 · Sep 6, 2019
Fixed: tree -NL 2 ~ >tree-2.txt
man 的话，暂不知道，你比如说从 https://github.com/man-pages-zh/manpages-zh 随便找一个带中文的。macos man 查看失败。

gIrl1990 OP @ysc3839 `tree -L 2 ~ >tree-2.txt` 会报 `col: Illegal byte sequence` 错误，源码找不到 `Illegal` 字样，233

`man find | col -b >m-find.txt` `tree -L 2 ~ | col -b >tree-2.txt` |
