Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
It may be a bug in your old version of IM, which is ancient at about 350 versions old. It could also be that you are not really pasting in the correct unicode characters. Try putting the text in to a file that supports unicode. Then use
draw "text 10,-20 '@filename'"
see if that works. But be sure your test editor is unicode compliant.
CORRECTION: I misread your draw command. The text 10,-20 was part of the text you wanted to print. So it must be in the text file. So the command is simply
-draw "@filename"
where filename is a text file that contains all the text you want to show.
When using the "@" format, I believe the file has to contain everything that would go between the outer quotes. See my page http://im.snibgo.com/snutf8.htm
