Mishandled Unicode text causes fail launch for localized CPL

Control Panel's Mouse applet (main.cpl) fails to launch when the translated characters don't all fit into an ANSI code-page. For Romanian, when (in order to mimic S with comma) S with cedilla is used (CP1250), it gets displayed properly and launches as it should (see "S-with-cedilla.png"). With the correct name (having S with comma written in it), the same applet name gets reduced as simple "S" (see "S-with-comma.png") and fails to launch with following messages:
err: (../../dll/win32/shell32/wine/control.c:468) Applet not found: Soricel
(../../win32ss/gdi/ntgdi/gdiobj.c:1169) GreDeleteObject: Trying to delete invalid object
