BigValue neutral symbol looks too much like negative sign

Number on the right in this example is positive 6%:

Potential Fix

Make symbol wider (use em dash instead of en dash). This ends up looking a bit wide in tables, but to solve this problem it's probably worth it.

Another option is making the symbol bolder, but we don't want to impact the visual effect from scanning the table quickly - the neutral items shouldn't be prominent.

Other option is changing the symbol, but that would likely disrupt the visual scan as well.

Actually the table issue could be solved by using an en dash if symbolPosition=right and em dash if symbolPosition=left

Have put this in as a temporary fix in #1825 until we decide on something longer term.

Another idea is to retain the up/down arrow, but color it grey. Possible all this behaviour should be configurable by the user.
