Simon commented on FREEMARKER-219:
----------------------------------
This seems to be related to how leading and trailing whitespace are handled.
So the following gives the expected output of 2:
{code:java}
${"1 3"?truncate_c(2, '')?length} {code}
While a different string of the same length incorrectly outputs 0:
{code:java}
${" 2 "?truncate_c(2, '')?length} {code}
Targeted tests for trailing and leading whitespace also incorrectly output 0:
{code:java}
${"1 "?truncate_c(1, '')?length}
${" 2"?truncate_c(1, '')?length} {code}
> truncate_c is not working as expected
