i just had a bit more of a tinker with comparing what Textmaker and Abiword RTF files look like when you open them as text and have made an interesting observation.

Use Textmaker to create a file that contains nothing more than the word "test" then save it as RTF.

If you try to open it with Abiword you should see the issue Smithy pointed out in the first post.

Now right cick that file and "open as text" so you can view it in Geany. At the bottom of the file you should see the word "test" preceeded by a "highlight0" spec. See pic 1 below. Note that there is no backslash following the "highlight" term.

Using Geany add a backslash and also change the number from highlight0 to highlight25 and click "save".

Now use Abiword to open the file and the problem should be gone (at least it is on my system...)

I experimented with various highlight values (highlight0, highlight3, highlight4 etc) and each value (except 0) gave a successful highlight that rendered the text visible. "25" was the one that seemed to remove the highlight completely and give white background.

I don't know if others can duplicate this but this is the behaviour I see on my system. (maybe locale dependent??)

I also just tried opening Smithy's test file from page 1 and i can make it readable by opening it as text in Geany and using the search function to automatically replace all occurrences of "highlight0" with "highlight25" then clicking "save"

Did not need to worry about backslashes.

Hi guys.

Here is a script that does what greengeek was doing manually above. Basically, an
RTF file has plain text in it, not html or xml code, so it can be parsed easily with a
Bash script.

I think the script is well commented, but if you have questions please ask them.
Also, please test on various RTF you may have, to provide more validations. TIA.

An illustration of the result is attached,using Smithy's test document. Also, the
replaceit utility, in 32-bit or 64-bit version, if you do not have it.

IHTH.

Ah, is that what it was? Well done Sherlock Holmes and Watson.

So if one clicks on a 'faulty' .rtf file, and docs sometimes, will it just load it up properly or am I jumping the gun a bit.

@greengeek

There's good research in your post above. Thanks.

Clever script musher Cool

- i had no idea i even had replaceit in my puppy but it's already there so the script worked fine.
I did not stick it in my PATH I just left it in the downloads directory along with Smithy's affected file and ran the following in a terminal:

This webpage offers some basic examples of how RTF handles highlight:

One example on offer is this:

Hello greengeek.

That should not be a problem if one uses the script to replace all "highlight0" expressions
with "highlight25" expressions.

ONLY "highlight0" expressions are changed -- not "highlight14" or "highlight7"
expressions--, so the other highlighting is not disturbed.

ALL "highlight0" expressions -- anywhere in the RTF document : at the top, in the middle
or at the very end, -- are changed.

I hope this answers your question.

BFN.
