vsh-table: Fix broken build on centos and rhel

The reason of broken build was that centos and rhel use older version of
glibc. These versions of glibc on these platforms cannot work with newer
unicodes, thus causing functions iswprint() and wcwidth() return
unexpected values causing the vshtabletest to fail. Therefore, let's
replace the new unicode characters causing issues with some older ones
to fix the test suite, as the issue would still persist during runtime.
