[Solved] Disconnected/Misaligned Square Root Symbol

Postby 00jonjon » Fri Oct 28, 2016 8:55 pm


I am writing an equation using in OpenOffice Writer, but the square root symbol is appearing disconnected in my equation. I have taken a screen shot of the equation in OpenOffice Writer, which can be seen in Figure 1. I was not sure whether or whether not the problem was unique to OpenOffice Writer, so I created an arbitrary equation in OpenOffice Math, and noted that the Square Root symbol was also disconnected, as can be seen in Figure 2. Please note that my OpenOffice version is 4.1.3, and my Operating System is Windows 10 with the build 14393.321.


How can I make the square root symbol connect to the line above the equation contained in the square root?


Here is the code I am using to create the equations.

Equation in Figure 1:
Code: Select all   Expand viewCollapse view
r_{~parallel~} = {n^2 cos(%theta) - sqrt{n^2 - sin^2(%theta)}} over
{n^2 cos(%theta) + sqrt{n^2 - sin^2(%theta)}}

Equation in Figure 2:
Code: Select all   Expand viewCollapse view
f(x)=sqrt(2x) +3


Here is a related post I found:

No solution is provided.


Bellow are is the odt file containing the equation that I am struggling with. There are also the figures that I used to explain the problem.

[Solved] Symbols font on Windows 8.1
There is discussion in that post which suggests that the same problem can affect Windows 10. I use a Mac and the equation looks OK to me so it may just be a font problem on Windoze systems. Read the link for solution details. I don't know if it will help with square root alignment.

Martin_g's amended OpenSymbol font fixes some problems in the Math formula editor. Try it!

It seems that there are some glyphs (characters/character components) missing in the original font file, so Math tries to find a suitable glyph in a different font. If that font does not match glyph size, you get those ugly gaps or crossovers. In that thread, martin_g says that he only added some missing glyphs to the already existing OpenSymbol font.

I followed keme's solution in the post above, installed the font, and it seems to have resolved the problem, as seen in figure 3 and figure 4 of this post. The code used for the equations in this post was the same as the code of the equations in my original post.


The solution that I propose is for OpenOffice 4.1.3 on Windows 10 - OS build 14393.321. It has not been tested on any other operating system.

1) Go to Martin_g's post as linked by keme above, and download the Open Symbol font.

2) Go to Control Panel -> Appearance and Personalization -> Fonts

3) Find the currently installed OpenSymbols font, and back it up via copy-paste to some location on your PC. This is a fail-safe in case the solution I propose does not work for you.

4) Copy paste (drag and drop) the download font into the Window showing the fonts on your PC. You should be prompted with a message to delete the currently installed OpenSymbols font that you backed up in step 3, and install the new font you are currently copy-pasting. Click OK.

5) Open up the file with the misaligned square root. Double click on the equation to make OpenOffice re-render it, as Martin_g suggests in his post. The square root should render properly now.

6) If the square root did not render properly, reinstall the font that you backed up in step 3 via the installation technique in step 4.


Bellow are the figures mentioned in the solution to the problem.

May I take the opportunity to thank you for such an excellent post describing your problem. It is precise, it describes the exact problem, it has images showing the problem, it references another post showing you have searched for an answer, and you have uploaded an example file - everything which is needed for analysis of the problem.

If only other posters could do the same :crazy:

Thank you.
