Liberation sans right arrow u2192 RIGHTWARDS ARROW is strangely small

[jdpipe]

Describe the bug
In LibreOffice and elsewhere, when using both Liberation Serif and Liberation Sans as the font, the RIGHTWARDS ARROW character u2192 '→' is strangley small. It does not conform to the typical positioning of most other fonts, and looks terrible. Normally, I have to copy and paste arrow with a different font, but this seems quite pointless and unnecessary -- perhaps the font could simply be corrected by changing the size/position of this arrow?

To Reproduce
Steps to reproduce the behavior:

1. Open up LibreOffice on either Ubuntu 20.04 or 18.04
2. Type the text as above, in one of the two problematic fonts.
3. See error

Expected behavior
See image above. Arrows should be positioned mid-height on the 'x' character, and with a width similar to an em dash.

Still having this issue on Ubuntu 23.04. See also https://pagure.io/liberation-fonts/issue/29

Arimo font, which is very similar, does not have this problem, fyi.

Also increase the line width of all arrows ←↓→↑↔↕↨⇔. In LO Calc (default size 10pt) they are hardly legible.
