Hi @eggrobin this branch/PR has pretty much all of the Unicode 15.1 beta changes for ICU: New property values (though not yet new properties), updated data & test data, collation...

Could you please try to implement the BreakIterator rule changes and add commits to this branch?

https://unicode-org.github.io/icu/userguide/dev/rules_update.html

The biggest change is the one for orthographic syllables:

Line breaking at orthographic syllable boundaries unicodetools#422
See also the ticket ICU-22039 and @aheninger's prototype at aheninger/icu@ortholb^...ortholb
- Partial notes from Andy last year:
- No ICU4J
- No LB tailorings
- RBBIMonkeyTest not updated. (There are two ICU RBBI monkey tests; the other one is updated.)
PAG-internal: https://groups.google.com/a/unicode.org/g/properties/c/IZ484tXVOHM
ICU-internal: https://groups.google.com/a/unicode.org/g/icu-team/c/qapZjIMFFso

There is also: Line breaking around « quotation marks »

Line breaking around « quotation marks » unicodetools#456

Was there something else in this area?
(I think we don't need to change ICU for the updated grapheme break rules because ICU already implemented those from CLDR.)

FYI @FrankYFTang

eggrobin · 2023-07-07T13:38:09Z

Could you […] add commits to this branch?

I cannot, probably because I do not have write access either to this repository nor to @echeran’s. echeran#48 has the changes.

markusicu · 2023-07-10T23:27:47Z

@echeran could you please rebase, and resolve the conflicts (jar files)? We should try to finish this soon.

See unicode-org#2492

Hooray! The files in the branch are the same across the force-push. 😃

@eggrobin it turned out that we just needed to refresh the Unicode 15.1 data in the ICU4J data jar file. Now, at least locally, we no longer see RBBI test failures. There are a few other failures that I think (hope) are not related to BreakIterator.

eggrobin · 2023-07-12T20:11:19Z

There are a few other failures that I think (hope) are not related to BreakIterator.

The ants seem happier, but Windows still seems sad.

Interestingly, I am now unable to build this branch on Windows:

29>NMAKE : fatal error U1077: 'C:\Users\robin\Projects\Unicode\icu\icu4c\source\extra\uconv\..\..\..\bin64\pkgdata.EXE' : return code '0xc0000135'
30>NMAKE : fatal error U1077: 'C:\Users\robin\Projects\Unicode\icu\icu4c\bin64\pkgdata.EXE' : return code '0xc0000135'

I do not see that error on CI, but I see this, which I would naïvely think suggests that something went wrong when building:

D:\a\1\s\icu4c\source\test\intltest\rbbiapts.cpp:1054 Built rules and rebuilt rules are different line

(I have no idea where to look beyond that.)

markusicu · 2023-07-12T22:30:51Z

@eggrobin @mihnita On a hunch, Elango and I fixed some charset encoding issues in C++ code, but most of the Windows builds still have rbbi test failures. For example, MSVC x64 Debug (VS2019) / Run x64 Debug Tests.

Linux & macOS pass. Java passes.
Windows MSVC on ARM passes.
Cygwin gcc fails, and the other Windows builds also fail.

Our best guess is still that it somehow has to do with Windows defaulting to the windows-1252 charset rather than UTF-8, and that maybe Windows-on-ARM and Robin's Windows machine are set to use UTF-8 as the default charset. But we apparently failed to stare down the problem in the code diffs. (If the charset is the problem, then somewhere a non-ASCII char * string is incorrectly assumed to be in UTF-8, or a non-ASCII char16_t * string or character is used where char * is needed.)

@rp9-next
@aheninger FYI

If this were indeed something about how the data files are built, then someone who has access to both a macOS or Linux machine, as well as a Windows machine with the windows-1252 default codepage, could check if the binary files (mostly .brk files) are the same.

eggrobin · 2023-07-13T00:46:07Z

Windows MSVC on ARM passes.

That one doesn’t have the Run Tests step, which is the one that fails, so I think that is a red herring.

I still have not managed to build this branch on my Windows machines (obviously it used to build before the rebase, with the RBBI tests passing), but I also can’t seem to build main, so I suspect I may have some local configuration that still thinks it is 73; my local issues are probably unrelated to the CI issues.

eggrobin · 2023-07-13T08:34:35Z

my local issues are probably unrelated to the CI issues.

Figured that out, the tools in icu4c\bin64 do not get replaced by new builds nor removed by cleaning. Manually removing that directory fixed it. I should fix the configuration of the Custom Build Steps that copy from icu4c\source\tools\whatever\x64\Release to icu4c\bin64 one of these days.

Having managed to build this branch… on my machine(s) it works:

maybe […] Robin's Windows machine[s] are set to use UTF-8 as the default charset

They are.

as well as a Windows machine with the windows-1252 default codepage

Hm. I can try messing with that setting.

eggrobin · 2023-07-13T10:07:26Z

Alright, setting my system to not-UTF-8, I can reproduce the failures:

eggrobin@9c6cc1c (which you will have to cherry-pick since I cannot push commits to this branch) fixes the tests.

We should file a follow-up ticket to read the rule files as UTF-8; they are already non-ASCII UTF-8 interpreted as whichever system codepage (the comments are not ASCII).
The fix to genbrk would be easy, see below; but something in TestRoundtripRules seems to need to be fixed separately.

Having hopefully figured that one out, I will put my system back to UTF-8 before something breaks.

mihnita · 2023-07-13T11:09:24Z

I've checked the icu4c/source/tools/genbrk/genbrk.cpp fix.
Confirm that it works, all tests pass, it does not look like TestRoundtripRules needs any fixing.

I applied the patch that @eggrobin included in his previous comment to modify genbrk (the alternative to editing the break rule files by escaping non-ASCII characters).

After the change, TestRoundtripRules is the only remaining test that fails.

So this is a change in behavior of this tool.
In a follow-up change, we should document (genbrk usage output, maybe User Guide) that genbrk looks for a Unicode signature byte sequence and otherwise assumes UTF-8.
