You can't insert a widget into the middle of a filter. But it doesn't
matter, you don't need it:
<$set name="initial" filter="[{!!title}lowercase[]]">
<$list filter="[tag[glossaire]prefix<initial>!prefix[é]]
[[tag[glossaire]prefix[é)]]+[sortan[]]">
</$list>
</$set>
In the first part of the filter I exclude é. In the second run, I ONLY
include é.
