When trying to convert UTF8 text or even plain-ascii into windows-1250 (cp1250), I get an empty string in PHP, and an error on command line. This happens on two of my machines with gentoo ~x86 which are administered in the same way, i downgraded glibc on the faster of them, and the error is same: a03-0431a ~ # echo 'aaa' | iconv -f ascii -t cp1250; iconv --version | head -n 1 iconv: illegal input sequence at position 0 iconv (GNU libc) 2.3.5 daniel ~ # echo 'aaa' | iconv -f ascii -t cp1250; iconv --version | head -n 1 iconv: illegal input sequence at position 0 iconv (GNU libc) 2.3.4 a03-0431a ~ # php <?php var_dump(iconv('ascii','cp1250','aaa')); ?> PHP Notice: iconv(): Detected an illegal character in input string in /root/- on line 1 Notice: iconv(): Detected an illegal character in input string in /root/- on line 1 string(0) "" Reproducible: Always Steps to Reproduce: 1. echo aaa | iconv -f ascii -t cp1250 Actual Results: iconv: illegal input sequence at position Expected Results: aaa Portage 2.0.53_rc5 (default-linux/x86/2005.1, gcc-3.3.6, glibc-2.3.5-r2, 2.6.13.1 i686) ================================================================= System uname: 2.6.13.1 i686 Celeron (Mendocino) Gentoo Base System version 1.12.0_pre9 dev-lang/python: 2.3.5, 2.4.2 sys-apps/sandbox: 1.2.13 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.20 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O3 -march=pentium2 -fomit-frame-pointer -mmmx" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O3 -march=pentium2 -fomit-frame-pointer -mmmx" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 apache2 authdaemond bcmath berkdb bzip2 calendar cli crypt ctype cups curl dba encode exif fam foomaticdb ftp gd gdbm gif iconv imap imlib ipv6 jpeg libg++ libwww lm_sensors maildir mhash mp3 mpeg mysql ncurses nls ogg pam pcntl pcre pdflib perl php png posix qt quicktime readline samba sasl session simplexml slang snmp soap sockets spell sqlite ssl syslog tcpd threads tidy tiff tokenizer unicode userlocales utf8 vorbis wddx xml xml2 xmlrpc xsl zip zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LDFLAGS, LINGUAS, PORTDIR_OVERLAY
works for me with 2.4 / 2.3.6: $ echo 'aaa' | iconv -f ascii -t cp1250; iconv --version | head -n 1 aaa iconv (GNU libc) 2.4 $ echo 'aaa' | iconv -f ascii -t cp1250; iconv --version | head -n 1 aaa iconv (GNU libc) 2.3.6 if it still fails, try rebuilding glibc with USE=-userlocales
