Hi,

My string is - " Año" and “Presentación” or “Joe$”

I want to remove ~ , ’ and $ from string in robot framework. There may be any uni code or special char in string and I want to remove all those chars from string.

Hi @bk-user

The [Unidecode](https://pypi.org/project/Unidecode/) module looks like it will do most of what you want to achieve:

```plaintext
***Settings***
Test Template	Convert Unicode Word

***Test Cases***

ñ	Año
ó	Presentación
$	Joe$
3	kožušček

***Keywords***
Convert Unicode Word
	[Arguments] ${originalword}

	${newword}= Evaluate	unidecode.unidecode("${originalword}") unidecode
	Log	${newword}

```

It didn’t do the $ sign but did the others, so depending how many other cases there are you could use a series of [Replace String](http://robotframework.org/robotframework/latest/libraries/String.html#Replace%20String)’s to handle the remaining few something like:

```plaintext
***Settings***
Library String

Test Template	Convert Unicode Word

***Test Cases***

ñ	Año
ó	Presentación
$	Joe$
3	kožušček
@	$p3c!@l

***Keywords***
Convert Unicode Word
	[Arguments] ${originalword}

	${newword}= Evaluate	unidecode.unidecode("${originalword}") unidecode
	${newword}= Replace String	${newword}	!	i
	${newword}= Replace String	${newword}	@	a
	${newword}= Replace String	${newword}	$	s
	${newword}= Replace String	${newword}	3	e
	Log	${newword}

```

Hi @bk-user

The [Unidecode](https://pypi.org/project/Unidecode/) python module is not installed by default, but I gave you the link that includes the install instructions. Like most python modules it’s just a pip install.

Dave.
