not work with some chinese symbol，such as 《》

What's the correct transliteration for the given symbol? Drupal core's transliteration service gives transliteration <<>>/, and those characters are not valid for URL, therefore they are removed.

Changed the priority to correspond the Drupal definition: https://www.drupal.org/docs/develop/issues/fields-and-other-parts-of-an-issue/issue-priority-field

thanks

I dont think there is a symbol in english for this one

just ignore it will be good or replace it with _

The Pathauto module works already like this, if the pattern (defined at /admin/config/search/path/patterns) is [node:title], the the page with title Test《》page, creates an alias testpage. If you want to replace the character (transliterated into < and >) with separator, you can define that on admin/config/search/path/settings under "Punctuation" details element.

ok，it wokrs，maybe its the title too long or some other modules problem
thank you very much
