non-english is broken

I made ggplot with label written by Korean character. ggplot shows Korean character labels well. but the labels are changed into '??' with image_graph. it seems like encoding problem. can I change the encoding in image_graph?

Can you please include example code so we can see the problem.

I had a similar problem when using image_annotate

smpl_img <- image_read("http://image.chosun.com/sitedata/image/201704/10/2017041001676_1.jpg")

image_annotate(smpl_img, "Clear Blue Sky", size = 70, location = "+50+200", color = "green")

image_annotate(smpl_img, url_encode("청명한 봄하늘"), size = 70, location = "+50+200", color = "green")

I think magick works perfectly fine. You just need to indicate "CJK-aware" font installed on your computer. url_encode() is designed for something entirely different. Don't expect it to ever work:

image_annotate(smpl_img, "청명한 봄하늘", size = 70, 
               location = "+50+200", color = "green", font = "Noto Sans CJK SC")

I figured this out by pasting your text into LibreOffice and it immediately suggested the valid font. This might not be as simple on Windows, I realize, but the problem is definitely not with magick. Please, see if you can reproduce and, if successful, please, close the issue.
