Spire.Office for Java is a combination of Enterprise-Level Office Java APIs offered by E-iceblue. It includes Spire.Doc for Java, Spire.XLS for Java, Spire.Presentation for Java, Spire.PDF for Java and Spire.Barcode for Java.

Developers can use Spire.Office for Java to perform a wide range of office document operations in Java applications, such as opening, creating, modifying, converting and printing Word, Excel, PowerPoint and PDF documents, generating and scanning 1D&2D barcodes.

As an independent Office Java library, Spire.Office for Java doesn't need Microsoft Office to be installed on either the development or target systems.

		If there is no XML available, first save an XML using saveFontFallbackRuleSettings and then manually edit the font replacement rules in the XML.
		The rules consist of three attributes: Ranges correspond to Unicode ranges for each character; FallbackFonts correspond to the font names for substitution; BaseFonts correspond to the font names for characters in the document.
		When editing the XML, it is important to note that the rules are searched from top to bottom for character matching.
		After editing the XML, load the rules using the loadFontFallbackRuleSettings method.
