It seems, that isn't good idea to turn off string checking at all in the
diagnostic function. LF, CR, BS and TAB are the essentials of the text
formating. So, those chars are there. The '\b' quite could produce a
bold printing, in past, for example :-) Sometimes, it needs to expand
TAB to spaces and etc. Other non-printed characters are optional things.
This is just _my_ opinion.  I think that minimalist set ('\n', '\r',
'\b', '\t') was the enough set for the diag_print() application.
