Bug#424984: openser: Insert Route HF (from Path) messes up if UTF-8 chars around

[Bernie Hoeneisen]

Package: openser
Version: 1.1.0-9etch1
Severity: normal
Tags: l10n

Hi!

I am testing the Path HF usage. When the usage of Path causes a
insertion of a Route HF and the (original) SIP INVITE request contains UTF-8
characters, the Route HF gets inserted at the wrong place, e.g. between
the <CR> and <LF> (Hexadecimal 0D and 0A) at the end of the From HF:

INVITE sip:bernie.hoeneisen at 192.168.1.3:6051;line=nfy9nuy8 SIP/2.0
Record-Route: <sip:127.0.0.1;r2=on;lr=on;ftag=as19d6b213>
Record-Route: <sip:130.89.10.194;r2=on;lr=on;ftag=as19d6b213>

(This example has been anonymized. Original available on request.)

The Hexadecimal code of the UTF-8 char is: C3 B6 (o with Umlaut)

I guess the detection for the anchor, where the Route HF has to be
inserted gets confused by the UTF-8 character.

cheers,
 Bernie
