International Components for Unicode (ICU)
How to reproduce the ICU NLS problem
- download the icu library
- build an empty main()
- add the trouble icu funcation call with NULL parameters
- check the function API document
- fill in all parameters

[1] Download
icu4c-67_1-Win32-MSVC2017.zip
https://github.com/unicode-org/icu/releases/tag/release-67-1
read the readme.html file to see how to build using VS 2015
This download has:
\lib
\include
\bin
icuin.lib, icuuc.lib
////////////////////////
Download the SOURCE CODE you then get the same stuff on work pc including the samples

Source code.zip
icu-release-67-1.zip
https://github.com/unicode-org/icu/releases/tag/release-67-1
But of course the source code zip does NOT have those dll’s.
[3] Confluence page has ICU building instructions?
[4] Need Visual Studio 2017 to build ICU 67?

UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, “fr_FR”, “GMT”, &status);

There are samples within the ICU source tree, under icu/source/samples – I think the converter samples there open and close utf-8, also icu/source/extras/uconv which is an ‘iconv’ like application.
