[#47790] - Article alias incorrectly includes commas when Unicode Aliases is enabled
- New
- Medium
- Build: 5.4-dev
- # 47790
What happened?
When Unicode Aliases is enabled in Joomla, creating an article with punctuation in the title generates an alias that keeps commas instead of removing them.
When Unicode Aliases is disabled, the issue does not occur.
Steps to reproduce
- Go to System → Global Configuration → SEO
- Enable Unicode Aliases
- Go to Content → Articles → New
- Add the following title:
My First Article, About Joomla Development
- Leave the Alias field empty
- Save the article
Version
6.1
Expected result
The generated alias should be: my-first-article-about-joomla-development
Actual result
The generated alias is: my-first-article,-about-joomla-development
The comma , is being included in the alias when Unicode Aliases is enabled.
System Information
Joomla Version: 6.1
PHP Version: 8.4
Database Version: Mysql 10.6.24
Additional Comments
When Unicode Aliases is disabled, the alias is generated correctly without the comma.
Aliases should automatically remove punctuation characters such as commas to create clean SEO-friendly URLs.

The root cause is in the joomla-framework/filter package - the stringUrlUnicodeSlug() method''s forbidden characters regex is missing the comma- This is why it only happens when Unicode Aliases is enabled.
Should I do a PR on https://github.com/joomla-framework/filter with the fix??

@krishnagandhicode Yes, please do that. If the issue happens also with Joomla 5.4, i.e. the 3.x-dev branch of the filter framework, make the PR for the 3.x-dev branch there. I will then be merged up into the 4.x-dev branch there. Otherwise, if the issue only applies to Joomla 6 / framework 4.x, make the PR for the 4.x-dev branch. Thanks in advance.
Thanks @richard67 for guidance.
Raised PR (joomla-framework/filter#85) for 3.x-dev as issue exited also for J5.

Thanks @krishnagandhicode .
@aboarken @BeginnerJoomlaCom Could you test that fix joomla-framework/filter#85 , preferably with 5.4, but 6.1 should also work, and report back there if your test was successful? Thanks in advance.
