Code points that have a bidirectional attribute of right-to-left (e.g.
some Arabic and Hebrew code points) were causing the code point to
render at the end of the search result, rather than the beginning. To
keep the results consistent, split the search results into two columns:
the first for the code point, the second for its name.
This works the same way as the command-line usage, searching against the
display name as provided by LibUnicode.
I've modified the search loop to cover every possible unicode
code-point, since my previous logic was flawed. Code-points are not
dense, there are gaps, so simply iterating up to the count of them will
skip ones with higher values. Surprisingly, iterating all 1,114,112 of
them still runs in a third of a second. Computers are fast!
This adds a TextBox along the bottom of the window. Double-clicking on a
character will append it to this box, which you can edit as any other
TextBox, or click the copy button to copy the output to the clipboard.
