ddd under utf-8 only partly loads files encoded in latin-1

From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830 Description of problem: when ddd loads a source code file encoded in latin-1 containing accented characters and is executing under the utf-8 locale it chokes on the first accented char and does not display any of the following text. This is extremely confusing to the user and makes the debugger impossible to use. Evidently latin-1 accented characters might be invalid utf-8 chars (just guessing here, don't know for sure). However UTF-8 allows for resync on ASCII chars and thus ddd should be able to recover from the error. I guess the problem is more in openmotif than ddd, but I did not investigate. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. save a C source file with "Bézier" in a comment, in latin-1 encoding 2. compile C file 3. open program in ddd 4. ddd displays the source file only up to the B of Bézier Actual Results: Part of the source code is not displayed, since source code viewer chops everything after the accented letter. Expected Results: The source file is displayed in its entirety (even though the accented char might be incorrectly undisplayed). Additional info: Ideally ddd should be able to autodetect the encoding of the source file (as vim or emacs), or a mechanism should be provided to select it.
An additional example of this problem is the DDD reference window. 1. Show the DDD ref. window by selecting in the menu Help->DDD Reference. 2. Scroll the bottom pane all the way to the end. The last thing displayed is "Dorothea L", under DDD Contributors, and nothing more. The character just after the L is an accented char (ü). As a result, all the interesting part of the DDD Reference cannot be seen. If ddd is started under an 8 bit locale (i.e. LANG=C) this problem does not appear. A quick workaround could be to set the locale to an 8 bit one (e.g., latin-1) upon ddd startup. Anyhow, as far as I know, ddd is not internationalized. Although this might have other implications.
it's fixed now in ddd-3.3.7-3, which will be available in rawhide soon. thanks fo your report.
