      Thanks a  lot for your answer, Matthew.

It seems resolve my problem ! I only use the new (compiled)  src/modules/rlm_linelog/rlm_linelog.c

./test_radtest_non_ascii.txt 
Sent Access-Request Id 71 from 0.0.0.0:34102 to 127.0.0.1:1812 length 79
	User-Name = "ｗｋｅ"
	User-Password = "hello"
	NAS-IP-Address = 127.0.1.1
	NAS-Port = 0
	Message-Authenticator = 0x00
	Cleartext-Password = "hello"
Received Access-Reject Id 71 from 127.0.0.1:1812 to 0.0.0.0:0 length 31
	User-Name = "ｗｋｅ"
(0) -: Expected Access-Accept got Access-Reject

and the  result of radiusd -X

We run a Freeradius 3.0.11 on an ubuntu 14.04. 
And il seems that one of our students find the way to put KO our server.
He tries to authenticate with a  user-name in non ASCII and
freeradius crash on the write ( in linelog module ) of
%{User-Name}

If somebody have an idea....
This was fixed in 1bb3ef53c98b.

Please try v3.0.x (or wait for 3.0.12, due soon).

Thanks,

Matthew
