#32958 [Fbk->Opn]: strtoupper/strtolower do not convert some 8859-2 characters

ID: 32958 User updated by: kirchner at cm-sec dot cz Reported By: kirchner at cm-sec dot cz -Status: Feedback +Status: Open Bug Type: Strings related Operating System: Linux Debian PHP Version: 4.3.10 New Comment: Hello, you can be right. I used your test program and output is: 0000000 0aa9 0000002 When I convert 0xaa9 to dec = 2729 and I write in Linux console <Alt>+<2729> I obtain the same character like when I write here <Alt>+<169>, which is dec from 0xa9. Both outputs are correct. When I change "str[0] to "str[0] = 0x61;" (letter "a") in main function of your program, I obtain 0000000 0a41 0000002 Jan Kirchner Previous Comments: ------------------------------------------------------------------------ [2005-05-05 20:21:44] rasmus@php.net Sounds like a locale bug to me. Could you compile this test program? #include <stdio.h> #include <locale.h> char *php_strtoupper(char *s, size_t len) { unsigned char *c, *e; c = s; e = c+len; while (c < e) { *c = toupper(*c); c++; } return s; } main(void) { char str[2]; str[0] = 0xb9; str[1] = 0x0; setlocale(LC_ALL,"cs_CZ"); puts(php_strtoupper(str,1)); } Just save it to s.c, for example and type: make s Then run it like this: ./s | od -x And add the output here. As far as I can tell 0xb9 gets uppercased to 0xa9 in 8859-2, so you should be seeing an a9 there in the output if your system's locale is working correctly. ------------------------------------------------------------------------ [2005-05-05 17:34:51] kirchner at cm-sec dot cz Description: ------------ Functions "strtolower" and "strtoupper" do not convert some Czech characters from 8859-2 charset. I tested it and I found, that these functions do not convert characters "š"/"Š", ""/"" and "ž"/"Ž", but other special Czech characters are converted correctly. Remark: We most often use two charsets in our country: ISO 8859-2 for Unix like systems and CP1250 (windows-1250) for Windows systems. Special Czech characters have the same hexadecimal value in both charsets except of mentioned characters (š,Š,,,ž,Ž). I thing, that my locale is set correctly. Here are three rows from output of the phpinfo() function. default_charset ISO-8859-2 ISO-8859-2 _ENV["LC_ALL"] cs_CZ _ENV["LANG"] cs_CZ Best regards Jan Kirchner ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32958&edit=1
