Unicode normalize filters?

Post by DFH » Wed Sep 06, 2017 7:39 pm

Any progress on the critical issues in the four Unicode normalize filters that I communicated to you by email several months ago?

Best regards,

David

The Help page libiconv (under Advanced Topics ) states:
About libiconv

libiconv is a GNU library used by TextPipe for some of its Unicode conversions.

C-Source code, .obj files and binaries are available for free from

http://www.gnu.org/software/libiconv/
It's incredible that the Unicode normalize filters have critical bugs if such a library is being used.

Still had no satisfactory explanation on this issue.

Best regards,

David

TextPipe 10.5 is being released today and uses the Windows Unicode libraries for these functions.

Please let me know how they go!

I tested the 26 x 26 x 4 digraphs again and it all worked as it should when converted to NFC.
i.e. No unwarranted spurious characters in the output.

There are further tests that I could do, but that can wait a while.

btw. Did you notify the supplier of the defective Unicode library that something was serious amiss?

Did no other TextPipe customer ever report the problem?

btw. Somebody told me last month that Microsoft had changed how they implement Unicode rendering in Windows 7 comapred to earlier versions of Windows.

They no longer use Uniscribe, even though that's is still being maintained.

See https://en.wikipedia.org/wiki/Uniscribe

and https://en.wikipedia.org/wiki/DirectWrite

Even so, there are some things that Windows 7 displays differently than the same text on Mac OS X.
Some glyphs in Biblical Hebrew are one application area where such differences are evident.

David

Hi David - we've removed the library in question from our build as it hasn't been updated in 2 years.
