In some languages, certain double characters (digraphs) are treated as a sinlge
letter. For example in Hungarian, the word "cselló" starts with the double
letter "cs". (For more examples, see
[[Latin_alphabet#Collating_sequence_with_extensions]].) This means that on
huwiki category pages like [[hu:Kategória:Vonós hangszerek]], "cselló" should
not be grouped together with words starting with the letter "c", but have an own
"cs" section.
This doesn't apply to foreign words (eg. "CSS" should be put in the "c"
section), and therefore cannot be decided automatically. An easy way to handle
it would be to use a special character in the category sort keys: eg.
[[Category:XXX|cselló]] would have the same effect as now, but
[[Category:XXX|cs,elló]] would create a section for words starting with "cs" in
the category page, and put it there.
Another use for this would be a more flexible categorization of numbers; see
[[Category:Stargate_SG-1_episodes]], where "A" is used for the 10th season.
Using the above markup, a "10" section could be created by using
[[Category:Stargate_SG-1_episodes|10,{{PAGENAME}}]].
