How do I get swedish characters in R

I am trying to do the map in ggplot2 in R. I use this function from rgdal package:

mapa <- readOGR(dsn=path.expand("C:/~/SWE_adm_shp"),layer="SWE_adm2")

than I do:

fortify(mapa)

ggplot(mapa, aes(x = long, y = lat, group = group)) +
  geom_polygon(fill = "blue", col = "white") +
  coord_map()

It works fine but when I look at the 

head(mapa)

I see that the names of the counties dont have the Swedish font (NAME_2)

ID_0 ISO NAME_0 ID_1         NAME_1 ID_2      NAME_2   HASC_2 CCN_2 CCA_2   TYPE_2    ENGTYPE_2
0  222 SWE Sweden    1 Östergötland    1   Ödeshög SE.OG.OD     0  <NA> Kommuner Municipality
1  222 SWE Sweden    1 Östergötland    2 Åtvidaberg SE.OG.AT     0  <NA> Kommuner Municipality
2  222 SWE Sweden    1 Östergötland    3     Boxholm SE.OG.BO     0  <NA> Kommuner Municipality
3  222 SWE Sweden    1 Östergötland    4   Finspång SE.OG.FI     0  <NA> Kommuner Municipality
4  222 SWE Sweden    1 Östergötland    5       Kinda SE.OG.KI     0  <NA> Kommuner Municipality
5  222 SWE Sweden    1 Östergötland    6  Linköping SE.OG.LI     0  <NA> Kommuner Municipality
  NL_NAME_2 VARNAME_2
0      <NA>      <NA>
1      <NA>      <NA>
2      <NA>      <NA>
3      <NA>      <NA>
4      <NA>      <NA>

How to work over that?

Try adding an encoding parameter to your read:

mapa <- readOGR(dsn=path.expand("C:/~/SWE_adm_shp"),layer="SWE_adm2", encoding = "UTF-8")

to specify the encoding of the character set your file uses. It's a good bet that it will be UTF-8.
