Re: Replace all occurrences of a specific character with another.

[PierGianLuca]

It looks like your character appears surrounded by non-letters in every 
instance. In this case you could use `query-replace-regexp` replacing

\<d\>

with

n

The "\<\>" brackets match beginning and end of words:

Backslash.html


Your character also seems to appear inside maths expressions only. In this case 
you could use the function defined in this post:

it's very useful and I use it regularly in LaTeX documents.

Cheers,
Luca
