Hyphenation dictionary will not load correctly if Firefox is installed to a unicode path on Windows
The current way we load hyphenation dictionaries is to call GetNativePath on a nsIFile. This method can fail on Windows, because on Windows not every file can be represented by a char*: the only reliable way to represent a file path is with a WCHAR*/PRUnichar*. http://hg.mozilla.org/mozilla-central/annotate/787ebf02a8c1/intl/hyphenation/src/nsHyphenator.cpp#l50 This can probably be fixed by bug 65537, but if not we need to modify libhyphen to take a windows-style path on Windows.

Depends on: 655337
As the code only uses very basic stdio calls to access the dictionary, it looks like we could easily #define those functions in the hnjalloc.h header (which is a custom mozilla version anyway) in order to work around the issue here without having to actually patch the hyphen.c source (which I'd prefer to avoid if possible). Here's a first attempt at a simple implementation - this replaces fopen, fgets and fclose (for the libhyphen code only) so that the string we pass to hnj_hyphen_load is a URL spec instead of just a pathname, and nsIInputStream is used to read from it - basically as Ehsan suggested in bug 655337 comment #6, point 3. This version avoids changing the API of hnj_hyphen_load (e.g. to take an nsIURI instead of a C string), so that we don't have to patch core libhyphen code. This should also provide a basis for loading hyphenation dictionaries from resource:// URLs referencing JARs, rather than individual files; as such, it's a first step towards fixing bug 655337.

Comment on attachment 559690 [details] [diff] [review] patch, use URI spec rather than utf8 file path to specify hyphenation dictionary Looks good to me.
