Hello.
I've been using the File component for years, and discover today a
strange exception when using a charset on a producer endpoint.
Example :
<route id="pma-file">
<from
uri="file:/TMP/PMA/input?delete=true&charset=UTF-8&moveFailed=.BUG"/>
<log message="PMA : processing ${file:name} (length ${file:length})..."/>
<to uri="file:/TMP/PMA/output?charset=ISO-8859-1"/>
</route>
If I put a file that contains only characters that exist in
ISO-8859-1, no problem.
If the file contains an € (euro) for example, an exception is thrown
(see at the end of the mail) :
java.nio.charset.UnmappableCharacterException: Input length = 1
A trivial java program, with the same jvm on the same machine, that
reads a file in UTF-8 and writes its content into another file with
ISO-8859-1 only replaces the missing unmapped characters with ?
Is it a bug (I can't imagine nobody saw that before) or just a missing
option on the endpoint ?
I've not found any option for that...
Thanks for your help.
Regards.
