Update utf8proc.[ch] to use the version now maintained by the Julia Language project (https://github.com/JuliaLang/utf8proc/blob/master/LICENSE.md). The license for the previous version was unacceptable for the Debian and Ubuntu release systems. The new version both updates the code and addresses the license issue. It turns out that the utf8proc software we are using was turned over to the Julia Language developers and the license terms changed to allow modification. (https://github.com/JuliaLang/utf8proc/blob/master/LICENSE.md). So the fix here is as follows: 1. Wrap the library with a fixed interface: libdispatch/dutf8.c and include/ncutf8.h. 2. Replace the existing utf8proc code with the new version from https://github.com/JuliaLang/utf8proc. 3. Add a couple more test cases: nc_test/tst_utf8_validate.c and nc_test_utf8_phrases.c. If/when I can find a usable normalization test, I will incorporate that later.

UAX15-D4. Stream-Safe Text Process
|
|
|
|
This is the process of producing a Unicode string in Stream-Safe Text Format by processing that string
|
|
from start to finish, inserting U+034F COMBINING GRAPHEME JOINER (CGJ) within long sequences of
|
|
non-starters. The exact position of the inserted CGJs are determined according to the following algorithm,
|
|
which describes the generation of an output string from an input string:
|
|
|
|
* If the input string is empty, return an empty output string.
|
|
* Set nonStarterCount to zero.
|
|
* For each code point C in the input string:
|
|
* Produce the NFKD decomposition S.
|
|
* If nonStarterCount plus the number of initial non-starters in S is greater than 30, append a CGJ to
|
|
the output string and set the nonStarterCount to zero.
|
|
* Append C to the output string.
|
|
* If there are no starters in S, increment nonStarterCount by the number of code points in S; otherwise,
|
|
set nonStarterCount to the number of trailing non-starters in S (which may be zero).
|
|
* Return the output string.
