how to use only unicode in nsis?

Question

I am evaluating nsis. I want to create an installer (using mui2) which will use the provided Unicode strings (for titles, buttons, labels etc.) and not to use any "localization".

For example: the application title contains unicode characters from different languages (let's say: " Λεξικό-Dictionary-Речник " will be the whole title, regardless of the user "language")

Is there a simple way to use the provided exact unicode strings independently of the mui language?

EDIT (as commented) : The above is about having own Unicode strings for buttons and, in general, UI text (no localization). Is not about any source (or destination) "filename" or "path".

Answer 1

NSIS will not translate the name, just make sure you save the .NSI source file as UTF-8 with BOM /Signature or UTF-16 with a BOM if you use non-ASCII characters.

Unicode True
Name "Λεξικό-Dictionary-Речник"
OutFile "MyInstaller.exe"
InstallDir "$ProgramFiles\$(^Name)"

!include MUI2.nsh

!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_FINISH

!insertmacro MUI_LANGUAGE English

Section
SetOutPath $InstDir
File /r "c:\myfiles\*.*"
SectionEnd

It is also possible to manually construct Unicode characters from Unicode code points:

Section
MessageBox MB_OK "${U+2115}SIS" # DOUBLE-STRUCK CAPITAL N + "SIS"
SectionEnd

Answer 2

The problem was I saved the file as UTF8 (!!!). After saving the file from Notepad as Unicode the problem disappeared.
