BabelMap 5.0.0.2 : Unicode in Colour
A new release of BabelMap which fixes certain problems that may be encountered by users of non-English locales when they select the option to display all styles of fonts. Many thanks to Nocturnal Dreamer for helping me get to the bottom of it all. John Cowan also had some good suggestions for improving the Composite Font Mappings dialog, but I'm afraid that I haven't been able to do anything about this yet.
On Friday someone somewhere mentioned that colour coding characters according to a selected property would be quite useful. I thought so too, so I have quickly added such a feature into the latest release. You can now select any of the following properties from the "Colour Coding" option of the "Options" menu, and each character in the BabelMap grid will then be highlighted in a particular colour according to the value of that property for the character. Even if you select no colour coding then you still get some colour coding now, as assigned characters will be displayed on a white background and unassigned code points will be rendered in grey.
- General Category
- Canonical Combining Class
- Bidi Class
- Bidi Mirrored
- Decomposition Type
- Numeric Type
- Script
- Unicode Version (when the character was encoded)
This, for example, is what the Basic Latin block looks like if you select colour coding by General Category :
The tables below show what colours are used for each value of the various properties other than Script. I'll leave it as an exercise to the reader to work out what colour I've used for each of the sixty-four scripts defined in Unicode 5.0.
