symbol as a message should have his meaning. defined in its method.

I come from China , My English is poor.

Hmm.. Then why it is so hard for you to comprehend such simple concept?
In Chinese you have thousands unique glyphs,

that you can use for writing, and each one has own meaning. Sometimes they literally mean something,

but sometimes the meaning depends on context.

That means that symbols '@#&%@#$' may not have meaning for most uses,

while for some other can. This depends on context.

��

Now if you take into account that in English, there's not so many glyphs for letter,

so you have to use combination(s) of them to form words, phrases etc.. that could have meaning

in specific context, while not have in other.

I don't know what you mean by "no meaning', they're symbols.
Try this in a Playground, it works in Pharo 5"

| oc sym filtered|
oc := ' one two�� three $%%&' splitOn: ' '.
sym := OrderedCollection new.
oc do: [:each | sym add: each asSymbol].
filtered := OrderedCollection new.
filtered := sym select: [ :each | each ~= #'' ].
Transcript show: sym printString; cr.
Transcript show: filtered printString; cr.
