I have a plain text file, ASCII, unix line breaks. 1 single line, and all that is in it is the word "radio".

Here's some test dialplan:

exten => 5,1,Verbose(Context: ${CONTEXT} Exten:${EXTEN})

    same => n,Set(feature=${FILE(/home/test/feature-1.txt,0,1,l,u)})
    same => n,Verbose(${feature})
   
    same => n,Set(featurefile=/home/test/feature-1.txt)
    same => n,Set(feature2=${FILE(${featurefile},0,1,l,u)})
    same => n,Verbose(${feature2})

Both should output "radio", right? Here's the output:

    -- Executing [5@fromvoipfone201:2] Set("PJSIP/6001-00000052", "feature=radio") in new stack
    -- Executing [5@fromvoipfone201:3] Verbose("PJSIP/6001-00000052", "radio") in new stack
radio

    -- Executing [5@fromvoipfone201:4] Set("PJSIP/6001-00000052", "featurefile=/home/test/feature-1.txt") in new stack
    -- Executing [5@fromvoipfone201:5] Set("PJSIP/6001-00000052", "feature2=radi") in new stack                                                         GAAAAARRRGGGHHHH!  ^^^^^

    -- Executing [5@fromvoipfone201:6] Verbose("PJSIP/6001-00000052", "radi") in new stack

And this is what's just at the top of the script. If I put it way down in another context:

    -- Executing [s@track-handler:3] Verbose("Local/s@root-00000026;2", "/home/test/feature-1") in new stack
/home/test/feature-1
    -- Executing [s@track-handler:4] Set("Local/s@root-00000026;2", "feature=radio▒▒") in new stack 
                                                    EVEN MORE GAAAAARRRGGGHHHH!  ^^^^^

[Oct 17 13:29:33] ERROR[5093][C-0000003c]: json.c:704 ast_json_vpack: Error building JSON from '{s: s, s: s}': Invalid UTF-8 string.

radio▒▒
    -- Executing [s@track-handler:6] GotoIf("Local/s@root-00000026;2", "1?radio▒▒,s,1") in new stack




So, at the top of the file, when it's just a straight file as the filename, it gives the full word. If the filename is a variable, it strips and character. And further down, same thing, but it adds two weird blocks, which appear side by side in the console, but weirdly, stacked up in this email.


(Oh, by the way, if there is more than one line in the file, even if I used "u" for line breaks, it adds a newline to the variable, Is that correct?)

What am I missing? I've opened it in both nano and notepad++, I've used iconv and all the tools I can think of to check that file, and all the asterisk conf files, too.
It all looks as it should here:

$ cat feature-1.txt
radio$ file feature-1.txt
feature-1.txt: ASCII text
$ wc -l feature-1.txt
0 feature-1.txt
wc -c feature-1.txt
5 feature-1.txt



After 6 hours struggling with this, I think I'm starting to lose the plot. Can anyone tell me where I'm going wrong? Thanks.
