Re: [Texmacs-dev] Bug with file names with special characters + solution (QT)

[Gubinelli Massimiliano]

Hi Miguel,

 could you be more specific on the difficulty you encountered? I've tried to open files with names like üöàéàî.tm and it works fine.

What do not work for you?

I do not fully master texmacs internals to tell you about encodings. As far as I understand strings are internally mostly encoded in ec (cork) with escapes for the form <XXXX> (this is called texmacs universal encoding) if I'm not wrong. There is part of the documentation which treats the source code. Some it is outdated but it will give you an idea of the main internal structures. 

Best

Well... more of a quick hack than a solution. There are way too many layers of string en/decoding for me to grasp right now, but changing line 301 inside qt_chooser_widget_rep::perform_dialog of qt_dialogues.cpp to read

        file = "(url-system " * scm_quote (cork_to_utf8(as_string (u))) * ")";

(i.e. reencoding the cork'ed string as utf8) and adding the necessary #include "converter.hpp" will enable TeXmacsQT to open .tm files with special chars (á,é,ü,ä,...) in their names. This wasn't working for me (SVN rev 3564).

I don't understand why, but applying the same change to the portion of the code which opens image files, a few lines above, will break it. Meaning I get a new error

TeXmacs] cannot read image file '/Users/miguel/whatever with á.jpg' in qt_image_size

 Although, by the way, I can't be sure because I can't see any images at all. All I get is a lot of

TeXmacs] warning: cannot render /Users/miguel/(blabla...)/misc/pixmaps/unknown.ps

This looks like I didn't compile ps support in or something, right? I would gladly investigate this issue further, but I'd need some help. For instance: what is the internal representation of strings? which encoding? which escaping? how does Scheme expect them to be?

Regards,
