test_formatting failure, ICU >= 72.1

Question

test_formatting failure, ICU >= 72.1

Closed this issue a year ago · 0 comments

The test_formatting.cpp unit test fails for boost 1.82.0 and for ICU version greater than or equal to 72.1 due to a change in ICU time formatting. Date-time conversion string compares fail because ICU now uses a three byte UTF-8 narrow no-break space character where before an ordinary single byte space character was used.

Note that other projects have experience similar unit test failures do to this ICU change, for example: node.

Here is the failure output:

Here is script that you can run on MacOS that will download ICU 73.1 and Boost 1.82.0, build and test ICU, build boost, and run the locale tests. The boost locale tests are expected to fail, as shown above.

#! /bin/zsh -x

# Download icu and boost to boost_local_test.d directory. Build icu
# and run tests. Build boost --with-locale and run locale tests.
#
# Expect results: PASS for ICU <= 71.1, FAIL for ICU >= 72.1
#
# The test failure is due to the introduction of the narrow
# non-breaking space characters in date/time conversions in icu 72.1.
#
# Tested with: MacOS 13.4, XCode 14.3.1
#
# Log file is written to: boost_locale_test.log
