ERROR: MethodError: Cannot `convert` an object of type Char to an object of type String

julia&gt; String('a')
ERROR: MethodError: Cannot `convert` an object of type Char to an object of type String

julia&gt; parse(String, 'a')
ERROR: MethodError: no method matching parse(::Type{String}, ::Char)
</code></pre>
