0X1A Is Not a Legal Xml Character

When you run the vwtool wobquery command on the work item, it indicates that the diacritics of the work item have been replaced by a “?”, and when you query the record directly from the database, it indicates that the character has been replaced by 0xa1. I replaced 0x1a with a hyphen (`-`) with the following method: Unicode code points in the following boxes are valid in XML 1.0 documents:[9] U+0009, U+000A, U+000D: These are the only C0 controls accepted in XML 1.0. U+0020âU+D7FF, U+E000âU+FFFD: This excludes some (not all) non-characters in the BMP (all substitutes, U+FFFE and U+FFFF are prohibited); U+10000âU+10FFFF: This includes all code points in the additional layers, including non-characters. As mentioned earlier, XML 1.0 only accepts a set of characters based on this. Work items that contain accent marks return the following error: “An invalid XML character (Unicode: 0x1a) was found in the content of the document item.” when opened using FileNet Workplace, FileNet Workplace XT, Business Process Framework (BPF), or a custom step processor. Quote from en.wikipedia.org/wiki/XML#Valid_characters Try inserting one of the problematic diacritics directly into a table in the database. If the incorrect character set is configured, 0xa1 is returned when the table is queried. Here is a useful Java method to ensure that a string is XML 1.0 compatible, it replaces invalid strings (all, not just 0x1a) with a specific replacement. To resolve this issue, the locale, code pages, and character sets of the various servers and users must be configured correctly to support the expected characters. The information on the database code page is obtained during the installation of the database software and depends on the language configuration of the operating system.

It must be configured to support languages added to the database when installing the database software. Therefore, the solution to this problem may be to ensure that the operating system code page and locale are set correctly, and then reinstall the database software. PE or later versions include a change that avoids the invalid XML error by allowing the process engine to filter ASCII surrogate characters when generating XML pages. This does not prevent the database from converting invalid characters to surrogate characters or removing them from the database. When running in PE or later, an occurrence of the character 0x1a in the database in the XML is replaced by “[!_26_!]”. The 26 is the decimal equivalent of 0x1a. The string {!_26_!] contains valid characters and is used to process the XML correctly. However, any invalid characters will still be lost. If the tests show that the current configuration allows you to enter diacritics in the NVARCHAR fields but not in the VARCHAR fields, you may be able to avoid reinstalling the database software.

PE 4.5.1 uses VARCHAR fields in the database schema. PE 5.0 does not. When Process Engine is migrated to version 5.0, the installer allows you to configure the type of data used in the schema. The issue can be addressed by upgrading to PE 5.0 and selecting the NVARCHAR data type for columns containing the diacritics. When I try to read it with the following code, I get an exception: com.thoughtworks.xstream.io.StreamException: An invalid XML character (Unicode: 0x1a) was found in the contents of the document item. The underlying cause of this issue is that the servers involved are not properly configured to support the character sets used. In this case, this will result in the appearance of a 0x1a character in a table. The XML error is returned because the character originally used in a text box to update the work item has been replaced by 0x1a in the database, and the characters 0x1a in the XML documents are invalid. 0x1a is the ASCII surrogate character and is used by the database to replace characters that do not match the configured character set.

For example, if a Microsoft® SQL Server database® is configured to process 7-bit ASCII in the United States and ā is inserted into a work item, database ā translates to 0xa1 when IBM FileNet Process Engine (PE) updates the record. Later, when the PE works with the object that contains the character 0xa1, users will see this exception when the XML form of the data is needed: “An invalid XML character was found in the content of the document element.” 0x1a is an invalid XML character. There is no way to represent it in an XML 1.0 document. Adding characters with accented characters, such as buttons or tildes, such as ā or ñ, results in the error message “An invalid XML character (Unicode: 0x1a) was found in the content of the document item” when the work item is displayed.
