That highly depends on your schema. Do you use <filter
class="solr.ISOLatin1AccentFilterFactory"/>?
I am using the following an it works like a charm
<fieldType name="stringSimilar" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" words="stopwords.txt"
ignoreCase="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ISOLatin1AccentFilterFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="false"/>
</analyzer>
<analyzer type="query">
<!--<tokenizer class="solr.LowerCaseTokenizerFactory"/>-->
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" words="stopwords.txt"
ignoreCase="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ISOLatin1AccentFilterFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="false"/>
</analyzer>
</fieldType>
