CharMapEx - Some kind of character map :-)

Story

This is a small tool that started as a private investigation into the functionality of some Windows API.

At some point somebody complained that GetGlyphIndices is not surrogate-aware and does not work for characters outside BMP (Basic Multilingual Plane).

So I have started a small application to test the claim.

And it was true!

So the next step was: “let’s find a solution!” and shortly after I had my own routine doing almost the same thing, but doing it’s own parsing of the cmap OpenType table.

To test that I needed an easy way to change the font and to visualize the results. Then I wanted to know what font contains a certain character (make sure to right-click :-)

And little by little, it grew into something that might be useful to others. And some friends also asked: “Why don’t you give it away?”

So, here it is, for your benefit and/or enjoyment :-)

Future plans:

  • Fix printing
  • Determine glyph presence using Uniscribe ( ScriptGetCMap)
  • Tile vertical and horizontal
  • Allow users to assign a font for each block
  • Take block names from the Unicode file “Blocks.txt”
  • Show Unicode information for each character using the Unicode files (“UnicodeData.txt,” Unihan.txt,” and maybe others)
  • Maybe publish some of the code

So make sure to select “Help” -> “Check for updates…” once in a while :-)

Ok now, there you go: CharMapEx.zip (contains the executable)

Good luck!
