== Test case
Create an ISO8859-15 text file, like e.g. {F3913570}
Use the following `~/.arclint` configuration:
```lang=json
{
"linters": {
"text": {
"type": "text",
"include": "(\\.txt$)"
}
}
}
```
Now try to lint.
This looks fine:
```
% arc lint jsonrenderer-test.txt
>>> Lint for jsonrenderer-test.txt:
Error (TXT5) Bad Charset
Source code should contain only ASCII bytes with ordinal decimal values
between 32 and 126 inclusive, plus linefeed. Do not use UTF-8 or other
multibyte charsets.
>>> 1 {"aaa": "a"}
```
This just outputs a newline, instead of an JSON-encoded linter message:
```
% arc lint --output json jsonrenderer-test.txt
```
It seems to me that the return code [[ /diffusion/ARC/browse/master/src/lint/renderer/ArcanistJSONLintRenderer.php;3b6b523c2b236e3724a1e115f126cb6fd05fa128$13 | here ]] is not checked.
== Other related problem
Further problem is that even `raiseLintAtPath()` adds context (start of the file) to the JSON renderer and will fail to encode any lint message in this case. Use this file (it is also containing merge conflict markers, so you can play with that linter, too, but this is not relevant for this test): {F3915626}
Use this `.arclint`:
```lang=json
{
"linters": {
"filename": {
"type": "filename",
"include": "(\\.txt$)"
}
}
}
```
Then run:
```
% arc lint jsonrenderer+test.txt
>>> Lint for jsonrenderer+test.txt:
Error (NAME1) Bad Filename
Name files using only letters, numbers, period, hyphen and underscore.
```
While JSON output is again a newline:
```
% arc lint --output json jsonrenderer+test.txt
```
Remove the offending chars and re-run:
```
% arc lint --output json jsonrenderer+test.txt
{"jsonrenderer+test.txt":[{"line":null,"char":null,"code":"NAME1","severity":"error","name":"Bad Filename","description":"Name files using only letters, numbers, period, hyphen and underscore.","original":null,"replacement":null,"granularity":1,"locations":[],"bypassChangedLineFiltering":null,"context":"<<<<<<<\n=======\n>>>>>>>\n"}]}
```
As you can see, it adds //context// and this is why it fails above with non-UTF-8 chars.
