JavaMail does not properly encode and decode filenames in non-ASCII character sets

admin — Fri, 20 Mar 2009 10:28:59 +0000

Applies to:
NA

Description:
Occurs while encoding and decoding filenames in non-ASCII character sets

Cause:
The filename is stored as a parameter in MIME headers. Encoded filenames of the form =?ISO-8859-15?B?5OTkLUluZm8ucGRm?= are not part of the MIME spec. A filename of the form =?A?B?C?= is a perfectly valid filename, not an incorrectly encoded filename. JavaMail does not encoded and decode filenames by default because doing so would violate the MIME spec.
The base MIME spec does not allow for encoding parameters. RFC 2231 defines a new way to include encoded paramters, including filenames, in MIME headers. It is not compatible with the de facto way that many applications illegally encode filenames. Even though JavaMail supports RFC 2231, that alone does not allow JavaMail to interoperate with these existing programs. As far as I know, very few existing programs support RFC 2231.
If you choose to violate the MIME spec, in order to interoperate with other programs that also violate the MIME spec, JavaMail gives you all the tools you need to do so. Starting with JavaMail 1.4, setting the System properties “mail.mime.encodefilename” and “mail.mime.decodefilename” to “true” will cause JavaMail to encode and decode the filename parameter.

UnsupportedEncodingException when invoking getContent() on a bodypart that contains text data

admin — Fri, 20 Mar 2009 10:28:59 +0000

Applies to:
NA

Description:
Occurs when invoking getContent() method on a bodypart that contains text data.

Cause:
Textual bodyparts (i.e., bodyparts whose type is “text/plain”, “text/html”, or “text/xml”) return Unicode String objects when getContent() is used. Typically, such bodyparts internally hold their textual data in some non Unicode charset. JavaMail (through the corresponding DataContentHandler) attempts to convert that data into a Unicode string. The underlying JDK’s charset converters are used to do this. If the JDK does not support a particular charset, then the UnsupportedEncodingException is thrown.
