[Qgis-user] replace '\' problem

[Werner Macho]

Hi,
As David already mentioned... Backslash is a special character and has to
be treated special.

Therefor you would have to write

replace("field", '\\', '.')

to replace a single backslash with a dot ..

special characters have to be "escaped"

Probably see
https://en.wikipedia.org/wiki/Escape_character
to find out.

regards
Werner
