Hi Mark, I'm attaching a patch to 'less-378' which corrects a problem with regards to composing as well as combining characters. Composing characters are characters that are in essence piggy-backed onto preceding characters and get displayed or super-imposed on them. Combining characters are similar except they functionally change the look-n-feel of previous characters and only come into operation if certain combinations of letters are present. In other words, composing/combining characters get folded into characters that proceeded them and as such 'less' should not account for them as taking up any room on the line/column. Here's an example (so that I don't sound like a lunatic :-) Assume characters X, Y, Z are composing characters (there are many of them according to the unicode spec) and I have the following sample of text. this is a tesXt, a veXYry simpZle test. (currently displayed as 39 characters - WRONG) The X, Y, Z characters will be displayed/super-imposed onto the characters they proceeded and so you will end-up with something like this, this is a teSt, a vEry simPle test. (with patch displayed as 35 characters - CORRECT) Sorry didn't know how else to show it to convey the idea. So why should 'less' care ? well 'less' should not count those characters as anything that takes up room on the line (they should be completely ignored if you will). In other words, if I have alot of them in a line, I get line-wrapping even though there is plenty of room. I can certainly send you screenshots and actual examples if need be, so don't hesitate to ask. BTW: I highly suggest you treat these multi-byte (mbyte) characters as a single entity (ie. combine their various mutli-byte sequences into a single encoded array entry) to simplify their treatment (I suggest that in the code in my comments). Do please inspect the patch (as it contains a 'hack' with regard to how the code is currently written) and do please consider including it (or something similar) at your earliest convenience. What's noted works for me without issue. Regards, - Nadim __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
