You can check how kcharselect totally skips from U+DFFF to U+F000, making seem like U+E000 doesn't exists.

SUMMARY
kcharselect is not displaying all the Unicode characters, it divides them by "blocks", but it skips some, particulary in the private area (U+E000 for example). The expected behavior was to display all the Unicode characters from a font, the font being used has special characters in the private area.

STEPS TO REPRODUCE
1. Use a font that has private characters in the U+E000 range for example.
2. Try to search for the character in the range.
3. You can search the character manually and add it to the bookmark, the character will appear and will be displayed, but after you bookmark it, the kcharselect will not redirect you to the character, in fact, it will do nothing.

OBSERVED RESULT
For step 2, You will see that the program totally skips the range, even if characters are available to be rendered in that range.

EXPECTED RESULT
The expected result was for the program to simply show all the ranges in the Unicode font, just like the Windows Char Map does (I had no problems with Windows Char map).
