Is there any way to search for articles that include a specific character in their name? For instance, suppose you want to find articles that include $, £ or € in their title. When I have tried to search for such characters in PubMed or Google Scholar, I fail to get any results.
For Google Scholar I believe it depends on which character you're after - regular letters are fine, but certain special characters (like $, @, and punctuation marks) are stripped from the submitted search query, and won't work. That is, that's the case for the regular Google, and while I haven't found official documentation stating this, as far as I can tell, Google Scholar has the same behavior.
PubMed replaces certain special characters (such as $) with spaces. See this help section.
