Cinnamon: text‐scaling‐factor cannot be set from command line

[Sadi58]

```

• Cinnamon 3.6.7
• Mint 18.3
• Intel Skylake
• 64 bit
  ```

The issue
The command gsettings set org.cinnamon.desktop.interface text‐scaling‐factor x.x does not work. The output is "No such key 'text‐scaling‐factor'" although there is such a key and it immediately takes effect if the value is changed via dconf-editor or System Settings > Fonts > Text scaling factor.

Steps to reproduce
Enter gsettings set org.cinnamon.desktop.interface text‐scaling‐factor 1.2 in terminal.

Expected behaviour
It should immediately change the setting accessible via dconf-editor or System Settings > Fonts > Text scaling factor.

Other information
This is important in handling certain issues related with HiDPI configuration in a scenario where user has a laptop which is sometimes connected to a external desktop monitor where a startup script is required to make some adjustments for the laptop display or the external monitor.

So weirdly if I copy/paste your text I get that error. However if I type it myself it works just fine.

@JosephMcc It fails here on fedora if I copy and paste it, the only difference is character encoding.
I doubt the issue is in the cinnamon code.

I don't really see this being a cinnamon issue either. Especially since it works here on git master. I'll reopen it if there is some more info providing showing the issue is actually with Cinnamon.

Hello, everybody.

@Sadi58: You are using the wrong character on text"‐"scaling"‐"factor. You are using the Hyphen character (UTF-8 representation 0xE2 0x80 0x90), when you should be using the Hyphen-minus character (UTF-8 representation 0x2D).

In short, text‐scaling‐factor is not equal to text-scaling-factor.

Thank you all!!!
And sorry for taking your time :-(
What a wierd thing. I copied this command from a website in English and pasted it into my login startup script.
When it didn't work I copied and pasted it to terminal and saw that puzzling message "No such key 'text‐scaling‐factor'".
I also tested this under Ubuntu 16.04 live session without any problem (but I had to enter the text manually that time ;-)
So I jumped to the conclusion that it might be a Cinnamon bug.
I should have tested it under a Linux Mint Live Session as well ( embarrassed emo here ; -)
Oh, these strange character and character encoding problems, they catch me unprepared from time to time...
