On a related topic (the list of code pointd in Unicode blocks) I would like to raise the question of the status of the four entries ulUnicodeRange in the latest version of the OS/2 table. This fifth version is given at http://www.microsoft.com/typography/otspec150/os2.htm
but it marked as a 'draft', at least in http://www.microsoft.com/typography/otspec150/.
This full list, appropriate to Unicode 5, should be used in Font editors, but I am told by the author of FontCreator, for example, that he awaits Microsoft's 'official' version. I wonder what is likely to change ?
As the number of Unicode blocks extends beyond 127 there will soon be needed a fifth ulUnicodeRange, for another 32 distinct blocks, like the four entries ulUnicodeRange at present. Has this been discussed ? There is nothing magic about the limit 128. Of course this is font technology, a separate question from Unicode lists.
Although one can read off the block ranges from the hundreds of pages of the Unicode manual, such a list, printed in a couple of pages of the Manual, would be helpful, like this.
