The ABNF (see below) acutally doesn't allow 0x20 as such. BUT, you are also
allowed to use LWS, which can contain spaces :)
header-value = *(TEXT-UTF8char / UTF8-CONT / LWS)
TEXT-UTF8-TRIM = 1*TEXT-UTF8char *(*LWS TEXT-UTF8char)
TEXT-UTF8char = %x21-7E / UTF8-NONASCII
UTF8-NONASCII = %xC0-DF 1UTF8-CONT
/ %xE0-EF 2UTF8-CONT
/ %xF0-F7 3UTF8-CONT
/ %xF8-Fb 4UTF8-CONT
/ %xFC-FD 5UTF8-CONT
UTF8-CONT = %x80-BF

Christer
