: Programming in C++ (Using Qt's QString) I am wondering what conversion to : apply before compiling words with such letters into the solrquery.
if you are implementing your own client and talking to Solr via HTTP then how you escape/encode characters in URLs is largely dependent on how you have your servlet container configured. For example... https://wiki.apache.org/solr/FAQ#Why_don.27t_International_Characters_Work.3F https://wiki.apache.org/solr/SolrTomcat#URI_Charset_Config One way to help debug what is going on is to use "echoParams=all" in your request, and then look at the "requestHeader" section of the response. that will echo back *exactly* what solr got from the servlet container for each of your input params. If you use it with the python response writer (wt=python) you will see escape sequences for any non-ascii characters -- which can be helpful for verifying the problem is in how the utf8 input is parsed, and not in how it is being returned to your client there is also an "example/exampledocs/test_utf8.sh" that is helpful for sanity checking these sorts of things independent of your client code. -Hoss
