Sqrt disappeared when exporting plot to PDF in version 10

Question

Bug introduced in 10.0.1 or 10.0.2 and fixed in 10.1.0

In version 10, if we plot with Sqrt in y-axis, and export to PDF, the square root disappears in the PDF file.

p = Plot[x, {x, 0, 1}, Frame -> True, 
  FrameLabel -> {"x", "\!\(\*SqrtBox[\(y\)]\)"}]

enter image description here

Export["test.pdf", p];

This does not happen in version 9.

I can reproduce this on OS X, v 10.0.0. Can you report this problem to support at wolfram.com? — Szabolcs, Jul 25 '14 at 21:16
Confirm it works in 9 but not in 10.0.2 (OS X 10.10.1). Incidentally if you want to use boxes in your labels it might be easier to do this {DisplayForm@SqrtBox["x"], DisplayForm@SqrtBox["y"]}.

Fixed in 10.1.0 but now I use MaTeX anyway ... motivated precisely by these types of problems. — Szabolcs, Apr 02 '15 at 02:54
@Szabolcs Thanks! It's nice to know MaTeX. I will have a try. — Yi Wang, Apr 02 '15 at 02:58
@Szabolcs the question you are referring to was posted months later than this question. — Sjoerd C. de Vries, Apr 02 '15 at 06:00
@SjoerdC.deVries I chose that one as the "main" one in the cloud of duplicates for two reasons: (1) it easier to see what's going on due to the screenshot (2) we already closed another question as a duplicate of that one tonight. Actually I didn't find this thread until later. I don't have a strong opinion on which one should be the main one, I just took the path of least resistance, to be honest .... — Szabolcs, Apr 02 '15 at 06:18
@Szabolcs: MaTeX is amazing... Thanks for posting the link. I can't believe I didn't know about this earlier. — JeffDror, Oct 02 '15 at 16:57

Looks like a bug. Stupid workaround:

Export["t:\\test.pdf", ImportString@ExportString[p, "EPS"]]

At the very least, there's a good chance that this would output reasonable vector graphics.

Or,

p = Plot[x, {x, 0, 1}, Frame -> True, FrameLabel -> {x, Sqrt[y]}]

The latter is what I usually do, anyway.

Thanks a lot! Very clever workaround :) I actually also tried the second method. However, my actual y-axis is quite complicated and I don't want Mathematica to automatically format the equation for me. So a string is preferred. – Yi Wang Jul 25 '14 at 21:58

The problem seems to be when the label is rotated. Check this:

Export["test.pdf", 
 ListPlot[{1, 2, 3}, Joined -> False, Frame -> True, 
  FrameLabel -> {Rotate["\!\(\*SqrtBox[\(x\)]\)", \[Pi]/2], 
    "\!\(\*SqrtBox[\(y\)]\)"}]]

however if you accept unrotated label, you can use:

Export["test.pdf", 
 ListPlot[{1, 2, 3}, Joined -> False, Frame -> True, 
  FrameLabel -> {"\!\(\*SqrtBox[\(x\)]\)", "\!\(\*SqrtBox[\(y\)]\)"}, 
  RotateLabel -> False]]
