CorelDraw x7 has the same issues as those discussed in "Latest CorelDraw X6 update BROKE output of WMF files (Windows MetaFile)" i.e. closing opened curves.
But also it produces poor quality EMFs. The lines are fine but the text letter spacing is bad, word have odd spacing, letters that are contained in a box in the CDR spill out in the EMF, words flow together etc. All in all the file is useless.
Has anyone else noticed this issue?
I have no use for an emf but I can understand your concern. See below. Simple Arial Bold with rectangle exported as emf then imported back.
