Talk:Strip control codes and extended characters from a string

This is very much like other tasks. How about stripping any set of chars from a string, the front, or the back of a string? --Paddy3118 07:03, 5 June 2011 (UTC)

This task is about all occurances. I hadn't planned on breaking it down to front, back and within the middle of the string. --Markhobley 10:20, 5 June 2011 (UTC)

We could always create an additional task "Strip control codes and extended characters from a string/Top and tail" with such details. --Markhobley 10:24, 5 June 2011 (UTC)

The reason I didn't go for "any sets of chars", is that the logic may be different. Control codes and extended characters may be filtered without a table lookup (on an ascii based system). I think it would be a good idea to create an additional task to "Strip characters not belonging to a set" to cover this. --Markhobley 10:40, 5 June 2011 (UTC)

The general task could be about stripping a set of chars from a string. For display purposes it would be easier to use something other than control codes as the example. Showing special facilities that a language has for stripping control codes and extended characters could be an optional requirement.--Tikkanz 12:09, 5 June 2011 (UTC)

Stripping a set of characters from a string is a good idea. I have create a separate task for that. --Markhobley 13:10, 5 June 2011 (UTC)

ASCII code 127 is a control character

I have updated the task description to be consistent with character code 127 being a control character. See also: http://www.lammertbies.nl/comm/info/ascii-characters.html or http://en.wikipedia.org/wiki/ASCII#ASCII_control_characters --Rdm 15:33, 6 June 2011 (UTC)
