You can do this by adding soft-hyphen (&#x00AD;) after each character on
which break can occur. You can add such characters automatically to your
FO output by XSLT. E.g.:

<xsl:template match="text()">
   <xsl:call-template name="hyphenate">
     <xsl:with-param name="content" select="."/>

<xsl:template name="hyphenate">
   <xsl:param name="content"/>
   <xsl:variable name="head" select="substring($content, 1, 1)"/>
   <xsl:variable name="tail" select="substring($content, 2)"/>
   <xsl:value-of select="$head"/>
   <!-- Place soft-hyphen after selected characters -->
   <xsl:if test="$head = '/' or $head = '_'">
   <xsl:if test="$tail">
     <xsl:call-template name="hyphenate">
       <xsl:with-param name="content" select="$tail"/>
