From d9c72e54190db2a0845d1558b5beb734e9f629ff Mon Sep 17 00:00:00 2001 From: =?utf8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Fri, 23 Jun 2023 17:24:11 -0600 Subject: [PATCH] test-gunicode: add new test to show that unichar_iswide() is borked I discovered this while looking at the tests with wide characters in the next patch. It's something to fix, but not directly relevant to the issue of skipping ANSI in ellipsization. We will generate output that is wider than expected in some cases, but wide characters are used very rarely so this isn't such a big problem. --- src/test/meson.build | 1 + src/test/test-gunicode.c | 27 +++++++++++++++++++++++++++ 2 files changed, 28 insertions(+) create mode 100644 src/test/test-gunicode.c diff --git a/src/test/meson.build b/src/test/meson.build index b57ba23539..ab0f091756 100644 --- a/src/test/meson.build +++ b/src/test/meson.build @@ -93,6 +93,7 @@ simple_tests += files( 'test-fstab-util.c', 'test-glob-util.c', 'test-gpt.c', + 'test-gunicode.c', 'test-hash-funcs.c', 'test-hexdecoct.c', 'test-hmac.c', diff --git a/src/test/test-gunicode.c b/src/test/test-gunicode.c new file mode 100644 index 0000000000..1836cdc04a --- /dev/null +++ b/src/test/test-gunicode.c @@ -0,0 +1,27 @@ +/* SPDX-License-Identifier: LGPL-2.1-or-later */ + +#include "gunicode.h" +#include "tests.h" +#include "utf8.h" + +TEST(unichar_iswide) { + char32_t c; + int r; + + /* FIXME: the cats are wide, but we get this wrong */ + for (const char *narrow = "abX_…ąęµ!"
