By the way, the 03 in your result is a bit spurious. For me it seems to
differ every time I run that code.
It happens with 0xE0 but not with e.g. 0xE6 (æ). It seems to be consistent
for every run though:
$ php -r 'for($a=0;$a<20;$a++)printf("%02x ",utf8_decode(chr(0xE0)));'
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
$ php -r 'for($a=0;$a<20;$a++)printf("%02x ",utf8_decode(chr(0xE0)));'
09 09 09 09 09 09 09 09 09 09 09 09 09 09 09 09 09 09 09 09
$ php -r 'for($a=0;$a<20;$a++)printf("%02x ",utf8_decode(chr(0xE0)));'
05 05 05 05 05 05 05 05 05 05 05 05 05 05 05 05 05 05 05 05
$ php -r 'for($a=0;$a<20;$a++)printf("%02x ",utf8_decode(chr(0xE0)));'
02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02
$ for a in
seq 1 20; do php -r 'printf("%02x
",utf8_decode(chr(0xE0)));';
done
07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 09 00
$ for a in seq 1 20; do php -r 'printf("%02x

done
08 00 00 02 00 00 00 00 00 05 00 00 00 05 00 00 07 00 09 00
$ for a in seq 1 20; do php -r 'printf("%02x

done
00 00 00 00 00 00 00 00 04 00 08 00 00 00 00 05 00 00 01 00
I don't think there is any reason for this behaviour. I'll file a bug.
