I now the asciifolding filter docs are really very clear on this, but it took me an embarrassingly long time to realise I was losing my currency symbol (£) to the ASCII folding filter. Other than creating my own character map with the char map filter, does there exist something of production quality that would translate accented UTF8 characters of the Latin-alphabet into non-accented characters in the ASCII range?

You are probably looking for ICU Folding which is part of ICU plugin: [GitHub - elastic/elasticsearch-analysis-icu: ICU Analysis plugin for Elasticsearch](https://github.com/elasticsearch/elasticsearch-analysis-icu) . It's not explained in details on that page, but you can see a long list of normalizations from the Lucene's Javadoc: [http://www.solr-start.com/javadoc/solr-lucene/org/apache/lucene/analysis/icu/ICUFoldingFilter.html](http://www.solr-start.com/javadoc/solr-lucene/org/apache/lucene/analysis/icu/ICUFoldingFilter.html) Overall, the explanation language is a little hairy and you may need to chase through the Unicode pages, but it should be the production-ready approach in the end.
