Description of problem: evolution mail crashes print preview / print in cairo Version-Release number of selected component (if applicable): evolution 3.20.5 How reproducible: Always Steps to Reproduce: 1. Start a new email. 2. Write "吳稚暉全集" in the content. Use Plain Text format. 3. Click either Print / Print Preview Actual results: Evolution crashes. Expected results: Printing works. Additional info: Seems to be related to cairo. I do recall xournal may suffer from similar issues when CJK characters are present in the text.

Thanks for a bug report. I can reproduce this in a virtual machine, but not in my real machine with Fedora 24. I also cannot reproduce it from gedit on both systems, thus it can be related to the way how webkitgtk3 encodes the string when printing. I'm moving this to webkit for now.
I tried env LANG=zh_CN evolution env LANG=zh_CN.gbk evolution Each time if I click on print preview it crashes. So regardless how Evolution think about local the printing crashes.
I can confirm if I try to print from epiphany a webpage that contains chinese. The same crash happens.
1. Launch webkitgtk3 2. Visit zh.wikipedia.org/ 3. Print to PDF. Result: The page crashes. Console output: WebKitWebProcess: cairo-array.c:182: _cairo_array_index: Assertion `index < array->num_elements' failed.
Sorry I meant epiphany.
OK, I can confirm the issue. I will look at it.
