A "functional" version without RunArray:
{{works with|Smalltalk/X}} (and others)

Most Smalltalk dialects include a class named "RunArray", which can be used as:
{{works with|Smalltalk/X}}
{{works with|VisualWorks}}
<lang smalltalk>compress := [:string |
String streamContents:[:out |
string asRunArray runsDo:[:count :char |
count printOn:out. out nextPut:char]]].</lang>
