** Windows 7 (Sublime Text 3): When Windows DPI Scaling is set to a value higher than 100%, the file name might not be displayed correctly, please try to add "dpi_scale": 1 to User Settings of Sublime Text.

** Linux (Sublime Text 2 & 3) and OSX (Sublime Text 3): You will need to install an extra plugin to make ConvertToUTF8 work properly: Codecs26 for Sublime Text 2 or Codecs33 for Sublime Text 3.


Using Package Control to find, install and upgrade ConvertToUTF8 is the recommended method to install this plug-in.

Otherwise, you can download this repository as a zip file, unzip it, and rename the new folder to ConvertToUTF8, then move this folder to Packages folder of Sublime Text (You can find the Packages folder by clicking "Preferences > Browse Packages" menu entry in Sublime Text).

Your folder hierarchy should look like this:

Please check ConvertToUTF8.sublime-settings file for details. You should save your personal settings in a file named "ConvertToUTF8.sublime-settings" under "User" folder. You can set project-specific settings (except encoding_list and max_cache_size) in the .sublime-project file which can be opened via "Project > Edit Project" menu.

  • encoding_list: encoding selection list when detection is failed
  • reset_diff_markers: reset diff markers after converting (default: true)
  • max_cache_size: maximum encoding cache size, 0 means no cache (default: 100)
  • max_detect_lines: maximum detection lines, 0 means unlimited (default: 600)
  • preview_action: convert the file's content to UTF-8 when previewing it (default: false)
  • default_encoding_on_create: specific the default encoding for newly created file (such as "GBK"), empty value means using sublime text's "default_encoding" setting (default: "")
  • convert_on_load: convert the file's content to UTF-8 when it is loaded (default: true)
  • convert_on_save: convert the file's content from UTF-8 to its original (or specific) encoding when it is saved (default: true)
  • convert_on_find: convert the text in Find Results view to UTF-8 (default: false)
  • lazy_reload: save file to a temporary location, and reload it in background when switching to other windows or tabs (default: false)
  • confidence: the minimum confidence rate which the converting will be performed automatic. (default: 0.95)


In most cases, this plug-in will take care of encoding issues automatically.

You can also use the "File > Set File Encoding to" menu entry to transform between different encodings. For example, you can open a UTF-8 file, and save it to GBK, and vice versa.


  • if convert_on_save is set to false, the file will NEVER be saved to the selected encoding
  • please do not edit the file before the encoding detection process is finished
  • please try either increasing the value of max_detect_lines or set the encoding manually if the detection result is not accurate
  • due to limitation of API, when lazy_reload is set to true, quit Sublime Text immediately after saving a file will cause the file to be saved as UTF-8, the correct content will be reload next time Sublime Text starts

Q & A

  • Q: It is not working after installation, how do I fix it?

    A: Please try the following steps:

    1. Restart Sublime Text
    2. Make sure the plug-in folder is named "ConvertToUTF8" (skip this step if you install via "Package Control")
    3. See Note section above

    5. Contact me
  • Q: Which encodings are supported?

    A: Any encoding supported by Python will be fine, other encodings like EUC-TW will not be supported.

  • Q: Why does the content become a mess when the window is re-activated?

    A: This is caused by reloading and has been fixed, please update your ConvertToUTF8 to latest version.

  • Q: Why does ST2 ask me that file "Has changed on disk. Do you want to reload it?" when the window is re-activated.

    A: Same reason as above. Please choose "Cancel" if you have unsaved changes to the file.

  • Q: When saving the file, Sublime Text tells me the file is saved as UTF-8, why?

    A: Don't worry, the plug-in will convert your file to original encoding.

  • Q: My file was saved as UTF-8 and it's in a mess, how can I recover it?

    A: Please open the file and make sure its encoding is UTF-8, then choose the menu entry "File > Save with Encoding > Western (Windows 1252)", close and reopen this file.
