I'm a PHP Developer by profession.

I'm using Windows 10 Home Single Language 64-bit Operating System on my laptop.

I've installed Sublime Text(Version 3.1.1, Build 3176) on my machine.

I checked for default character-encoding into file C:\Users\lenovo\AppData\Roaming\Sublime Text 3\Packages\Default\Preferences.sublime-settings

and I found

"default_encoding": "UTF-8",

Now, I want to change it to "ISO-8859-1". I even tried to edit this file but I couldn't. The file is not editable.

So, asking for help from you great people.

Please help me out.

Thank You.

On menubar, choose Preferences -> Settings and change the Preferences.sublime-settings -- User file like image below:


Restart Sublime Text after saving settings.

NOTE: If opened file is already in encoding other than the default, Sublime Text will continue to using that encoding.

  • I tried making the said change "default_encoding": "ISO-8859-1" in the file "C:\Users\lenovo\AppData\Roaming\Sublime Text 3\Packages\User" but still it doesn't work. It's taking the default value "default_encoding": "UTF-8" only. Why so? – JSLover Nov 9 at 7:12

  • Thanks for your updated answer. But, I'm getting some strange result now. I added "default_encoding": "ISO-8859-1" in the file "C:\Users\lenovo\AppData\Roaming\Sublime Text 3\Packages\User" and checked the set encoding using built-in PHP function mb_detect_encoding("str"); but surprisingly instead of getting "ISO-8859-1" as a output result I got "ASCII". Why so? – JSLover Nov 9 at 8:08

    You need to specify encoding detection order in mb_detect_encoding where "ISO-8859-1" is detected first, see here. – Mark J. Adams Nov 9 at 8:40
