wide option prints matches in wide instead of non-wide/ascii

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Default output of string matches to non-wide/ascii instead of wide so that 
it's human readable when extracted from a wide match.

What is the expected output? What do you see instead?
domain.com instead of the wide output of something like smi.o
$ value instead of @ wide value

What version of the product are you using? On what operating system?
latest and greatest on ubuntu.

To add onto this issue, YARA appears to be hitting on an ASCII match, but 
printing the string results as unicode.

test file (in ASCII):
TESTING
ONETWO
YARATHREE

Rule1:
rule test
{
 strings:
   $s0 = "test" nocase ascii wide
   $s1 = "yara" nocase ascii wide

 condition:
   $s0 and $s1
}

Execution:
yara -s rule.yara test.txt
test test.txt
0x11:$s1: YR
0x0:$s0: TS

Change rule to remove "wide" from strings:

Rule1:
rule test
{
 strings:
   $s0 = "test" nocase ascii 
   $s1 = "yara" nocase ascii 

 condition:
   $s0 and $s1
}

Execution:
yara -s rule.yara test.txt
test test.txt
0x11:$s1: YARA
0x0:$s0: TEST
