 Standalone installer for QGIS 3.12 'București' incorrectly displays the
 release name as Bucure?ti instead of București, at least on Windows 10 64
 bit localised in Italian.

 The same doesn't occur with the standalone installer for QGIS 3.10 'A
 Coruña'.

 This is probably caused by the fact that while the ñ char (U+00F1 Latin
 Small Letter N with tilde) is mapped in the Latin-1 Supplement and
 Windows-1252 codepage, whereas the ș char (U+0219 Latin Small Letter S
 with Comma Below) is not.

 Moreover, the standalone installer for QGIS 3.12 incorrectly sets the
 following Values in the Windows Registry:


 {{{
 VersionName = "Bucure?ti" in HKLM\SOFTWARE\QGIS 3.12

 DisplayName = "QGIS 3.12.0 'Bucure?ti'" in
 HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\QGIS 3.12

 }}}

 I have done some tests, and it seems that it is possible to solve the
 problem in the following way (building the installer on Windows):

 1.
 a. use NSIS version 2.50.0-Unicode
 (https://github.com/jimpark/unsis/releases)
 or
 b. use NSIS version 3.05 and add the option Unicode true in QGIS-
 Installer.nsi

 2.
 and in the creatensis.pl perl script, use the modules
 Win32::Unicode::Process and Encode qw(decode) and change the system calls
 to makensis as:


 {{{
 $cmd = decode( "UTF-8", "makensis -DINNER=1 -DUNINSTALLERDEST='$instdest'
 -DINSTALLER_NAME='makeuinst.exe' $args" );
 systemW($cmd);

 }}}


 {{{
 $cmd = decode( "UTF-8", "makensis -DINSTALLER_NAME=$installerbase.exe
 $args" );
 systemW($cmd);
 }}}
