To check if you have non-ASCII characters you can remove all ASCII chars from a string and check whether the result is empty. First create a string variable which contains all valid characters:

<xsl:variable name="ascii-chars">&#32;!...01234568789..ABCD...abcd...</xsl:variable>

For the test you would use the translate() function:

<xsl:if test="translate(., $ascii-chars, '') = ''">
...
</xsl:if>

To change non-ASCII chars to ASCII chars you have to know which characters to change. This is easy if you know the input is ISO-8859-1 or some other limited range of characters. You would use the translate() function.

If any valid UTF-8 char could be in the input, there is no easy solution, because in many languages single characters can only be transliterated to more than one ASCII character.
