breakLines not working as expected

Hello,
I use Latte 2.11. breakLines
filter doesn't seem to work :
$question = 'Please answer the following math question.\nHow much is 7 + 3 ?';
<label for="antispam_answer">{$question|breakLines}</label>
The result is :
Please answer the following math question.\nHow much is 7 + 3 ?

Hi, I have tried it and figured that \n
needs to be a proper
character, not a text. If you use single-quotes, then it's just a text, with
double-quotes it's a unicode character (U+000A).
If you have some text stored somewhere, try replacing '\n'
with
"\n"
before using breakLines
.

Actually the string comes from a INI file and is handled with
parse_ini_file
and vsprintf
.

The source of the string does not matter.
What matters is that the string does not contain character with ASCII code 10
(new line), but rather two separate characters with ASCII codes 92 (backslash)
and 110 (lower case letter “n”). If you want to make breakLines
work, you need to convert the string yourself:
\str_replace('\n', "\n", $stringFromIniFile)
should to
the trick.
Function parse_ini_files()
does not support standard escape
sequences, as noted in the documentation: Note that the ini parser doesn't support
standard escape sequences (\n, \t, etc.). If necessary, post-process the result
of parse_ini_file()
with stripcslashes()
function.
