Most of the cases there is an issue while adding Joomla article with Special charecters(á, é, Á, ñ).
It can be simply fixed by the below steps.
===========================================
Find the loaded php.ini file
--------
php -i | grep php.ini
--------
Then find the below lines
===========
[mbstring]
mbstring.language = "English"
mbstring.internal_encoding = "UTF-8"
mbstring.http_input = "auto"
mbstring.http_output = "pass"
mbstring.encoding_translation = On
mbstring.detect_order = "auto"
mbstring.substitute_character = "none"
mbstring.func_overload = 0
==========
Here the "mbstring.encoding_translation" need to be off for special character support. So the correct one is.
==========
[mbstring]
mbstring.language = "English"
mbstring.internal_encoding = "UTF-8"
mbstring.http_input = "auto"
mbstring.http_output = "pass"
mbstring.encoding_translation = Off
mbstring.detect_order =
mbstring.substitute_character = "none"
mbstring.func_overload = 0
==========
===========================================
Now we can add article with Special characters in Joomla.
So easy but difficult to locate the fix...
