1. When you make a change in the code you have to remake the format file
(context —make en).
2. When you write many lines in the form “blocks[<name>] = { first=…, last=… }”
you do only replace the previous setting but don’t add new entries to the
table.
3. Part of the problem is mess in unicode because the symbols you need are
scattered, see http://www.unicode.org/charts/PDF/U1D400.pdf and here
