Given
http://en.wikipedia.org/wiki/Basic_Latin_unicode_block
defines the characters up to the tilde, this can
be done with a character range.

I like Michael's and David's suggestion better to
use Unicde classes, but below is what I threw together quickly.

. . . . . . . . . . Ken

T:\ftemp>type tom.xml
<doc>?????H1N1??</doc>
T:\ftemp>call xslt2 tom.xml tom.xsl
<?xml version="1.0"
encoding="UTF-8"?><doc><other>?????</other><latin>H1N1</latin><other>??</othe
r></doc>
T:\ftemp>type tom.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                version="2.0">

<xsl:template match="text()" priority="1">
  <xsl:analyze-string select="." regex="[!-~]+">
    <xsl:matching-substring>
      <latin><xsl:value-of select="."/></latin>
    </xsl:matching-substring>
    <xsl:non-matching-substring>
      <other><xsl:value-of select="."/></other>
    </xsl:non-matching-substring>
  </xsl:analyze-string>
</xsl:template>

<xsl:template match="@*|node()"><!--identity for all other nodes-->
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

</xsl:stylesheet>

T:\ftemp>rem Done!
