Try this:
{{!!char_name}}<$list filter="[<currentTiddler>has[alias]]">, alias:
{{!!alias}}</$list>
Notes:
* the has[alias] operator only returns the currentTiddler if the alias
field is non-blank
* if you wanted to allow a blank alias field (but still require the field
to exist), use has:field[alias] instead
