	If I understand the example correctly, you're asking which
languages have optional contractions in the standard written form,
because ever language I've come into contact with has spoken contrac-
tions which are not reproduced in writing.  For example, although I
often include the words "y'all's", "gonna", "what'll", etc. in letters,
I would hesitate to use them in formal writing.
	
	One sees various forms when writers try to reproduce people's 
natural speech, but the only standard contractions in German are (native 
speakers help me out):

1)  Elision of unstressed "e" under certain conditions, particularly in 
the word "es" (it).  For example, "Wie geht's?" (But "Wie geht es Ihnen?"  
That is, contraction is acceptable with the informal "you" only).  In other 
cases (Wie geht's? is a fixed expression) it is optional, such as "Keiner 
merkt's" or "Sie hat dich nicht gesehn" (for "gesehen").

2)  Contraction of certain forms of the article with certain prepostions.
These are:  ans (an+das), am (an+dem), aufs, beim, durchs, fuers, ins, im, 
uebers, vom.  (Have I forgotten any?)  Other similar contractions, such as 
"ueberm" or "vorm", are heard in speech but unacceptable written.
These contractions are all optional.  Generally, they are made whenever the
article is not stressed, e.g. "Es ging durchs Fenster" vs. "Es ging durch
DAS Fenster" (roughly, "through the window" vs. "through THAT window").

3)  The intial vowel of the forms of "ein" (one, a) is dropped.  Common in
speech (esp. so'n "such a"), but I believe it's inacceptable in all but the
most informal writing.  Optional.

	Italians have more leeway; they need only invoke the principle of
euphony.  "oli" (oils) for "olii" is a common contraction.

	Welsh has a large number of prepostion/pronoun contractions some of
which are colloquial, some of which are archaic.  The picture's much too
messy to go into here.  Certain languages, especially Romance ones, have
"short" forms for certain verbs.  For example, Catalan has "hem" for "havem"
(we have) and there are similar cases in Romanian.

	Korean has a wide variety of optional contractions, but I have no
idea which are acceptably written because I learned spoken forms.
A very common example is the "possessive" suffix written "-ui" (a high, back, 
unrounded vowel with a high, front, unrounded off-glide; Yale transcription) 
which is normally pronounced [e^].  It can contract with some subject 
pronouns, e.g. naui or nay [ne^] (my), neui or ney [ne] (your), etc.
	There are various contractions with the "object" suffix -(l)ul, such
as "kel" for "kesul" (it), and _lots_ of verb contractions, most of which are
optional in writing. 
	 
 	I hope this wasn't too much :>
