Figured me had a 'typo' in tui-conf-set, i went to fix it.
Now, i also figured, it might be nice to have tui-conf-set report (to console, not only exit code) wether it could save the variable to the file or not.

gensprep
gensprep(8) ICU 50.1.2 Manual gensprep(8) NAME
gensprep - compile StringPrep data from files filtered by filterRFC3454.pl SYNOPSIS
gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ] DESCRIPTION
gensprep reads filtered RFC 3454 files and compiles their information into a binary form. The resulting file, <name>.icu, can then be read directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library. The files read by gensprep are described in the FILES section. OPTIONS
-h, -?, --help Print help about usage and exit. -v, --verbose Display extra informative messages during execution. -c, --copyright Include a copyright notice into the binary data. -s, --sourcedir source Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA. -d, --destdir destination Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA. ENVIRONMENT
ICU_DATA Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/. Some tools in ICU depend on the presence of the trailing slash. It is thus important to make sure that it is present if ICU_DATA is set. FILES
The following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal- izationCorrections.txt. rfc3453_A_1.txt Contains the list of unassigned codepoints in Unicode version 3.2.0.... rfc3454_B_1.txt Contains the list of code points that are commonly mapped to nothing.... rfc3454_B_2.txt Contains the list of mappings for casefolding of code points when Normalization form NFKC is specified.... rfc3454_C_X.txt Contains the list of code points that are prohibited for IDNA. NormalizationCorrections.txt Contains the list of code points whose normalization has changed since Unicode Version 3.2.0. VERSION
