SUMMARY
When I inspect a font like EB Garamond (https://github.com/georgd/EB-Garamond)
with many characters for niche use cases, like historical floral hearts, I'd
like to easily find out a symbol's code point. When I select a preview of the
type "Unicode Block", I get a popup with this information when I hover with the
cursor over the symbol.  However, there is no popup when one select the "All
Characters" preview type.


STEPS TO REPRODUCE
1. Open e.g. /usr/share/fonts/LiberationSans-Regular.ttf in kfontview
2. Select "Unicode Block: Basic Latin" as preview
3. Hover over character
4. Select "All Characters" as preview
5. Hover over character

OBSERVED RESULT
In the first case, one gets a popup with information like this:

Category Letter, Uppercase
UCS-4                          U+ 41
UTF-16                        0x 41
UTF-8                          0x41
XML Decimal Entity  A

In the second case, there is no such popup.

EXPECTED RESULT
The same popup, regardless of preview type.
