It's not clear to me from any of the comments you've made in this thread
wether you've ever confirmed *exactly* what you are getting back from
solr, ignoring the PHP completley. (ie: you refer to "UTF-8 for all of the
web pages" suggesting you are only looking at some web application which
is consuming dat from solr)
What do you see when you use something like curl to talk to solr directly
and inspect the raw bytes (in both directions) ?
For example...
$ echo '[{"id":"HOSS","fr_s":"téléphone"}]' > french.json
$ # sanity check that my shell didn't bork the utf8
$ cat french.json | uniname -ap
character byte UTF-32 encoded as glyph name
23 23 0000E9 C3 A9 é LATIN SMALL LETTER E WITH
ACUTE
25 26 0000E9 C3 A9 é LATIN SMALL LETTER E WITH
ACUTE
$ curl -sS -X POST 'http://localhost:8983/solr/collection1/update?commit=true'
-H 'Content-Type: application/json' -d @french.json
{"responseHeader":{"status":0,"QTime":445}}
$ curl -sS
'http://localhost:8983/solr/collection1/select?q=id:HOSS&wt=json&omitHeader=true&indent=true'
{
"response":{"numFound":1,"start":0,"docs":[
{
"id":"HOSS",
"fr_s":"téléphone",
"_version_":1475795659384684544}]
}}
$ curl -sS
'http://localhost:8983/solr/collection1/select?q=id:HOSS&wt=json&omitHeader=true&indent=true'
| uniname -ap
character byte UTF-32 encoded as glyph name
94 94 0000E9 C3 A9 é LATIN SMALL LETTER E WITH
ACUTE
96 97 0000E9 C3 A9 é LATIN SMALL LETTER E WITH
ACUTE
One other cool diagnostic trick you can use, if the data coming back
over the wire is definitely no longer utf8, is to leverate the "python"
response writer, because it generates "\uXX" escape sequences for
non-ASCII strings at the solr level -- if those are correct, that helps
you clearly identify that it's the HTTP layer where your values are
getting corrupted...
$ curl -sS
'http://localhost:8983/solr/collection1/select?q=id:HOSS&wt=python&omitHeader=true&indent=true'
{
'response':{'numFound':1,'start':0,'docs':[
{
'id':'HOSS',
'fr_s':u't\u00e9l\u00e9phone',
'_version_':1475795807492898816}]
}}
