non ascii characters in doc and manpage

[Terrance]

you are using all kinds of unicode characters in docs and examples.

it took me 2 hours of hopeless debugging to figure it out.

all these "‐"s you are using are not \x2d, but \xe2\x80\x90.

then the `netplan generate` keeps through errors about
```
Invalid YAML: inconsistent indentation:
```
on the next line.

e.g.

```
network:
renderer: networkd
vrfs:
  vrf1:
    table: 1
    interfaces:
      ‐ enp5s0
    routes:
      ‐ to: default
        via: 10.10.10.4
    routing‐policy:
      ‐ from: 10.10.10.42
```

is

for whatever's sake, PLEASE REPLACE THEM!

Hi,

Interesting, can you confirm if this happened only when you copied the example from the man page?

Our web docs and example files are all ASCII files and apparently work fine. But I can confirm that if I copy it from the (rendered) man page, the dash character is not ascii.

[Danilo Egea Gondolfo (danilogondolfo)]

Ok, according to man-pages(7), we need to write \- in the man sources if we want the ascii dash.

[Danilo Egea Gondolfo (danilogondolfo)]

It's impacting searches in the man page. Other man pages seem to escape the - (\-) everywhere.

[Terrance (terrance-hhh)]

hmm, I see `/usr/share/man/man5/netplan.5.gz` is using unescaped `-`, and no extended characters. so it is **man** converting '\x2d' into '\xe2\x80\x90'.

[Terrance (terrance-hhh)]

**man** converts unescaped '-' in /usr/share/man/man1/man.1.gz, too!
