With a long lines, if the text is found for the right of the screen, viewer doesn't make horizontal scroll to the found text.

How to reproduce:

1. Open file with long lines (Makefile of MC is good for this) in non-wrap mode.
2. Try search '-Wno-long-long' text.
3. Search is successful, but found text is not shown in the screen, because it is located at 235 column. but screen width is less than 235. Viewer made vertical scroll only to the line with found text.

• Blocking set to #2283

(In #2283) Replying to egmont:

The logic that modifies col (e.g. col += width, col -= width etc.) assume that width and bytelenght are the same notions (because col actually means offset in the file), hence does not handle UTF-8 or CJK (double width) characters correctly.

Yes, this is the known issue. At least the #2132 ticket requires such fix.

In the wrapped mode, it doesn't scroll down to the found fragment, either.

Any chance to get it fixed (12 years old!), at least for the ASCII character set?
