Did you run a quick test with JCE Editor? IIRC they do something different with their extension name

JCE looks fine with this PR, except for the package itself.

The string is present in pkg_jce_2633/language/en-GB/en-GB.pkg_jce.sys.ini
but the code in the loadTranslationFiles($extension) method does not provide for this case.

Excellent news :)

I wonder though if it is possible to add such a case. When JCE is installed, the result in the installation manager is coming from
COM_JCE_XML_DESCRIPTION="<p>JCE is a WYSIWYG Editor Extension for Joomla based on Moxiecode's <a href='http://tinymce.moxiecode.com' target='_blank' />TinyMCE</a> editor.</p><p>JCE would not exist without these great projects:<br /><ul><li><a href='http://www.joomla.org' target='_blank'>Joomla!</a></li><li><a href='http://tinymce.moxiecode.com' target='_blank'>TinyMCE</a></li><li><a href='http://jquery.com' target='_blank'>JQuery</a></li><li><a href='http://getuikit.com/' target='_blank'>UIKit</a></li><li>Fugue Icons Copyright © <a href='http://p.yusukekamiyamane.com/'>Yusuke Kamiyamane.</a> All rights reserved.</ul></p><p>JCE is dedicated to my father.</p><p>For a full changelog see <a target='_blank' href='https://www.joomlacontenteditor.net/support/changelog/editor'>https://www.joomlacontenteditor.net/support/changelog/editor</a></p>"

and not from the package language file.

EDIT: In any case, the <name> in JCE's component manifest is uppercase. Therefore this patch is absolutely necessary.

yup - I have much experience in getting the translated extension names and you will find example after example of 3pd doing some 'interesting' things that need working around if it's to be rock solid.

my current code is belt and braces (and has J1.5.x workarounds too)
https://github.com/PhilETaylor/myjoomla-connector/blob/master/bfnetwork/bfExtensions.php#L191

That's overkill imho, and not taking care of packages. ?

I found that JCE is storing its en-GB.pkg_jce.sys.ini in the frontend language folder.
But I do not know if the placement there as well as the name of the package PKG_JCE are standards.
If it's only JCE, no use to make it a special case in our method.

no use to make it a special case in our method.

Like I said, there will be LOTS of these "special cases" over time ;-) 3pd do all kinds of wonderful and weird things :) Good luck ! :-)
