Perhaps you know most of this already but here's some information
anyway. The name is "Pavel Janík" and it displays just fine in my
system. File fringe.el is UTF-8-encoded.

When encoded in UTF-8 the character í (U+00CD) consists of two bytes,
0xC3 and 0xAD. When some system interpretes those bytes as separete
ISO-8859-1-encoded characters they are à (0xC3) and a soft hyphen
(0xAD). This is what your system seems to have done:

So it sounds like some kind of singlebyte-multibyte encoding problem.
