Is there an RTL or package equivalent for _wcsicmp et all <http://msdn.microsoft.com/en-us/library/k59z8dwe.aspx> or should the libc declaration be added to the application ? Or is there another recommendation to compare wide (so-called Unicode) strings case-insensitive ?

The closest equivalent is probably sysutils.UnicodeCompareText(). It uses CompareStringW on Windows though, and on Unix it converts both strings to uppercase, locale-sensitive-wise, and compares those.

As a general rule it is better to convert to lower case before comparing Unicode characters. Accents can get lost in conversion to uppercase. Accent loss does not happen or is much more rare in conversion to lower case.
