<0xa0> appears in document

[Matthew Hill]

I am processing Transcription documents from a vendor. When some of the documents, not all, are processed the last line may contain a special character seen as <0xa0>. The last line may have other text besides the special character. I’m trying to use regsub to replace the character with a NULL with no luck. It seems as if regsub passes over the special character like it is not even there. Does anyone have any suggestions on how to search and replace this special character?

have tried using the following in a copy command with a counter to find the last line to interogate:

set res $xlateInVals

regsub -all {[^[:print:][:punct:][:blank:],%,$,^.*,+,=,~]} $res {} res

set xlateOutVals

Matthew,

First thing is xlateInVals is a list. use some sort of list notation to get the first element of xlateInVals (if there is only one element).

Also, I don’t think a0 hex is any of the normally defined special characters so you might need to include xa0 in your regsub.

1. xlateInVals is a list, so your 1st statement should look more like:

set res [lindex $xlateInVals 0]

2. Your regular expression is not correct

3. I’m not sure I understand why you put result between “><", but I assume that's what you need

It would be good if you could include example of your document

Your regexp syas that anything that is *NOT* one of those characters to change to empty string.  That would not leave you much.

I don’t know if this is Hex A0 or literal you are seeing but you don’t even need regsub.

set inp [lindex $xlateInVals 0]

set xlateOutVals

]

or if literal

set xlateOutVals

]

Can you do an hcihd on the message to find out what the hex representation of the character is?

Also can you ask the vendor if they have a coding error?

Maybe they meant instead of .

I don’t see why you cannot use string map

set res [string map {xa0 ”} [lindex $xlateInVals 0]]

Agree re: string map, just used a similar approach successfully:

set xlateOutVals
