From 0720a06a7518c9d0c0125bd5d1f3b6264c55c3dd Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 17 Nov 2011 16:42:19 -0500 Subject: NLS: improve UTF8 -> UTF16 string conversion routine The utf8s_to_utf16s conversion routine needs to be improved. Unlike its utf16s_to_utf8s sibling, it doesn't accept arguments specifying the maximum length of the output buffer or the endianness of its 16-bit output. This patch (as1501) adds the two missing arguments, and adjusts the only two places in the kernel where the function is called. A follow-on patch will add a third caller that does utilize the new capabilities. The two conversion routines are still annoyingly inconsistent in the way they handle invalid byte combinations. But that's a subject for a different patch.
