hyphenation inside block in FOP works only for pure alphabetical characters
Last modified: 2012-04-07 01:52:02 UTC
Hyphenate does not work correctly when the data in the block has numeric characters or commas... In the example below, only the data in the first table-row gets hyphenated correctly <?xml version="1.0" encoding="UTF-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:datetime="http://exslt.org/dates-and-times" writing-mode="lr-tb" text- align="start" role="html"> <fo:layout-master-set> <fo:simple-page-master master-name="all-pages" page-width="8.5in" page- height="11in"> <fo:region-body margin-top="1in" margin-right="0.25in" margin- bottom="1.5in" margin-left=" 0.25in" page-width="8.5in" page-height="11in"/> <fo:region-before region-name="page-header" extent="1in" display- align="before"/> <fo:region-after region-name="page-footer" extent="1.5in" display- align="after"/> <fo:region-start extent="0.25in"/> <fo:region-end extent="1.5in"/> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="all-pages"> <fo:static-content flow-name="page-header"> <fo:block font-size="14pt" text-align="center" hyphenate="true" language="en" space-before.conditionality="retain" space-before="0.5in"/> </fo:static-content> <fo:static-content flow-name="page-footer"> <fo:block font-size="small" text-align="center" hyphenate="true" language="en" space-after.conditionality="retain" space-after="0.5in"/> </fo:static-content> <fo:flow flow-name="xsl-region-body"> <fo:block hyphenate="true" language="en" role="body"> <fo:inline>Hyphenation for this table data works - when all the data is non numeric</fo:inline> <fo:table> <fo:table-body> <fo:table-row> <fo:table-cell> <fo:table> <fo:table-body> <fo:table-row> <fo:table-cell border-width="1pt" border-style="solid"> <fo:block hyphenate="true" language="en">HyphenationOfThisBlockWorksNicelyUnlessWhenThereIsNoCommaOrNumeri cDataBeforeIt</fo:block> </fo:table-cell> <fo:table-cell><fo:block/></fo:table-cell> </fo:table-row> <fo:table-row> <fo:table-cell border-width="1pt" border-style="solid"> <fo:block hyphenate="true" language="en">HyphenationOfThisBlockWorksNicely,OnlyForTheBlockBeforeTheCommaIn TheBlockData</fo:block> </fo:table-cell> <fo:table-cell><fo:block/></fo:table-cell> </fo:table-row> <fo:table-row> <fo:table-cell border-width="1pt" border-style="solid"> <fo:block hyphenate="true" language="en">12345678901234567890123456789012345678901234567890123456789012345 6789012345678901234567890</fo:block> </fo:table-cell> <fo:table-cell><fo:block/></fo:table-cell> </fo:table-row> </fo:table-body> </fo:table> </fo:table-cell> </fo:table-row> </fo:table-body> </fo:table> </fo:block> </fo:flow> </fo:page-sequence> </fo:root>

I think I see the problem here, but I'm not sure it's a bug... Not all of it, that is. Hyphenation is, in fact, only applicable to pure alphabetical characters. Strictly speaking, one cannot 'hyphenate' a seven-digit number, if I interpret correctly. That said, the case with the comma maybe could be handled better. Currently, from the point on where the hyphenator meets the comma (or more generally: any non-letter), it does not even attempt to hyphenate anymore. What you're really looking for is unconditional wrapping of the text, rather than hyphenation, it seems. That would be wrap-option="wrap" on the blocks, which we claim to support according to the compliance page. After having a quick try, this feature seems to be broken, however...
