Package: libc6-dev Version: 2.19-17 Severity: normal Dear Maintainer,
In Greek traditional text analysis, the iota subscript (U+0345) is often talked about as a "diacritic", see: "http://en.wikipedia.org/wiki/Iota_subscript"; In the recourse: http://www.unicode.org/ucd/ I found two documents: 1. http://www.unicode.org/Public/UCD/latest/charts/CodeCharts.pdf 2. http://www.unicode.org/Public/UCD/latest/ucd/PropList.txt In the first document in the section: "Combining Diacritical Marks" I found this character in the table. See at the screenshot https://yadi.sk/i/F_A04mo7gRMvd. In the second document in line 752 we have: 0300..034E ; Diacritic # Mn [79] COMBINING GRAVE ACCENT..COMBINING UPWARDS ARROW BELOW As a result, I think, it is pretty clear that iswalnum(0x345) should not return 1, but rather 0. To test the function iswalnum(), I created a simple code: === #include <stdio.h> #include <locale.h> #include <wctype.h> #include <inttypes.h> #include <stdlib.h> #include <string.h> #define HAVE_CONFIG_H 1 int main (int argc, char** argv) { if (!setlocale(LC_CTYPE, "")){ perror("setlocale(3) failed"); return 1; } wchar_t wc; mbtowc (NULL, NULL, 0); mbtowc(&wc, argv[1], strlen(argv[1])); printf("iswalnum(0x%" PRIxMAX ")=%d\n", (intmax_t) wc, iswalnum(wc)); return 0; } === I put this code in a file test4iswalnum.c, then compiled: $ gcc -Wall -o test4iswalnum test4iswalnum.c Then I check the function iswalnum(): $ LC_CTYPE='C.UTF-8' ./test4iswalnum ͅ iswalnum(0x345)=1 -- System Information: Debian Release: 8.0 APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.32-042stab105.14 (SMP w/1 CPU core) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages libc6-dev depends on: ii libc-dev-bin 2.19-17 ii libc6 2.19-17 ii linux-libc-dev 3.16.7-ckt7-1 libc6-dev recommends no packages.
