Alter messages in Drupal 7

Question

There is a couple of messages in drupal. When there is a php warning, an error message is raised, but a module can also raise messages with drupal_set_message(). The question is: Is there a way to alter these messages? For example to replace every 'a' with 'b' in every message.

Thanks!

While there is no message alter on set, you can change them on display via hook_preprocess_status_messages, see http://api.drupal.org/api/drupal/includes--theme.inc/function/theme/7 on preprocess and http://api.drupal.org/api/drupal/includes--theme.inc/function/theme_status_messages/7 .

Edit: also you can try string overrides check http://api.drupal.org/api/drupal/includes--bootstrap.inc/function/t/7 , in short $conf['locale_custom_strings_en']['some message'] = 'some messbge'; for English, change _en for something else if it's not English.
