[Testing] potential encoding issues

Saving sub_concatenate_r31_data.qvs with 1252 encoding is interpreted as
a either a binary or one line of chinese characters. This does not
happen to other scripts.

This commit saves the file as UTF-8, containing only a few fields (which
again contain Nordic characters) to verify that this is corrupted during
a revert.
Revert "[Testing] potential encoding issues"

This reverts commit bb333b6c51269e1b3ca981dae90fc7a4c8817aaa.
Add tranfrom scripts to create_daily_shiftdata

IMPORTANT NOTE: The following files are stored as UTF-8 encoded text
files, as the 1252 versions showed up as binary and/or chinese in Git,
apparently depending on content. These files will be garbled by Qlik
when running, and the etl script WILL FAIL if run as-is. Do a search and
replace on the files or open and re-save them as 1252 locally before
running.

The encoding issue is hopefully a Qlikview bug that will be sorted soon.
