Question:

How do I get ExtremeZ-IP 3 to work with Adobe Acrobat Distiller? Certain files placed on an ExtremeZ-IP server from Mac OS X cannot be distilled.

Answer:

Adobe Acrobat Distiller has limitations about the characters that can be present in filenames. Specifically, Distiller will not operate on filenames containing decomposed unicode characters. Unicode characters can be represented in two different formats: precomposed, where complex characters are encoded as a single character, like ” “, and decomposed, where those characters are encoded as multiple characters, like “o “. Mac OS X uses decomposed unicode encoding by default, so files placed onto an ExtremeZ-IP server will be in a format that Adobe Distiller cannot understand.

To address this issue, ExtremeZ-IP 3.2 supports an optional registry key that can configure ExtremeZ-IP to convert decomposed unicode filenames into precomposed format, so that Distiller can properly read them. The key, CreatePrecomposedMacRoman, will change the default ExtremeZ-IP behavior. By default, this setting is disabled. It may be enabled by setting a DWORD value of 1. A DWORD value of 0 (zero) will disable this functionality. This key must be created from the following registry location:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ExtremeZ-IP\Parameters\

Note that even with this feature enabled, there can still be files put onto an ExtremeZ-IP volume from Mac OS X that cannot be distilled – characters that are not in the 256-character Windows character set are not readable by Distiller. This has nothing to do with the interaction between Mac OS X and Windows, but is a limitation of the Distiller application itself. Some examples of characters that cannot be used: square root (√), integral (∫) and partial differential (∂).

The supplied ZIP file contains a registry file that allows users to automatically update their Windows registry to enable this feature, when using ExtremeZ-IP 3.2.2. To use it, please refer to the enclosed ExtremeZ-IP Registry Readme.txt file.

Note: ExtremeZ-IP 4.0 and above automatically convert all file names to pre-composed Unicode and do not have this issue.
