How can I change the default encoding when sourcing?

[Auderson]

A while ago, a window pop up asking me the default encoding for sourcing, and I selected UTF-8. Now everytime when I source a file, there is "encoding = 'UTF-8'" in the function, and it cause errors.
So how can I reset this? There is no "encoding = 'UTF-8'" in the function before I changed that setting. BTW, it seems there is no such settings in global options.

Go to RStudio >> Preferences and select Code. From there select the Saving tab from the top (see below)

When you click on Change... a prompt will open that allows you to either select a different default encoding, or select "[Ask]" to choose an encoding each time:

Thanks, but that won't work.
Anyway I've reinstalled rstudio, and it's solved.

If your question's been answered (even if by you), would you mind choosing or marking a solution? (See FAQ below for how).

Having questions checked as resolved makes it a bit easier to navigate the site visually and see which threads still need help. It also saves someone from spending time to respond to a problem that you've already resolved.

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …
