You can do this by adding soft-hyphen (­) 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:call-template>
</xsl:template>
<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 $head = '_'">
<xsl:text>­</xsl:text>
</xsl:if>
<xsl:if test="$tail">
<xsl:call-template name="hyphenate">
<xsl:with-param name="content" select="$tail"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
