It is an UTF8 issue, it will need some time to understand why
the code page interpretation is wrong for R and it is not using UTF8

As work around:

$ tar -xf DBI-1.1.3.tar.gz

$ cd DBI-1.1.3

$ grep Mü DESCRIPTION
     person("Kirill", "Müller", , "krlmlr+r AT mailbox DOT org", role = 
c("aut", "cre"),

$ sed -e "s/Müller/Mueller/" -i DESCRIPTION

$ grep ller DESCRIPTION
     person("Kirill", "Mueller", , "krlmlr+r AT mailbox DOT org", role = 
c("aut", "cre"),

$ cd ..

$ tar -xzf DBI-1.1.3.tar.gz DBI-1.1.3

and then in R:

 > install.packages("/tmp/DBI-1.1.3.tar.gz", repos = NULL);
Installing package into ‘/usr/lib/R/site-library’
(as ‘lib’ is unspecified)
* installing *source* package ‘DBI’ ...
** using staged installation
** R
** byte-compile and prepare package for lazy loading
** help
*** installing help indices
** building package indices
** installing vignettes
** testing if installed package can be loaded from temporary location
** testing if installed package can be loaded from final location
** testing if installed package keeps a record of temporary installation 
path
* DONE (DBI)

PS: I see only 1.1.3 on https://github.com/r-dbi/DBI/releases
