Bonjour,

je rencontre un petit probl�me de traduction sur un terme de
typographie, � collating elements � dans :
 
| Two additional special sequences can appear in character lists.  These
| apply to non-ASCII character sets, which can have single symbols (called
| collating elements) that are represented with more than one character,
| as well as several characters that are equivalent for collating or
| sorting purposes: 
| 
|     Collating Symbols 
|        A collating symbols is a multi-character collating element
|        enclosed in ``[.'' and ``.]''.  For example, if ``ch'' is a
|        collating element, then [[.ch.]] is a regexp that matches this
|        collating element, while [ch] is a regexp that matches either
|        ``c'' or ``h''. 
|     Equivalence Classes
|        [...]
 
Il semblerait d'apr�s la description que cela concerne des symboles
compos�s de plusieurs caract�res, comme "oe" ou "ae". Ces � collating
elements � seraient-ils des � ligatures � ?

Dans ce contexte, j'ai trouv� un article sur un algorithme de
"collation", qui permet de classer de tels symboles par rapport aux 26
lettres classiques de l'alphabet. http://www.dbazine.com/gulutzen1.html 
Il y est dit : 
 � A collation is a set of rules for comparing character-string values. 
   Other terms for the same thing are sort order and linguistic comparison, 
   but "collation" is the official SQL:1999 word. � 
 
Alors, � ligatures �, ou � �l�ments d'ordonnancement / d'�quivalence / de
comparaison linguistique � ? Ou existe-t-il un terme plus appropri� ?

Merci,
