I have an App that writes "Unicode-encoded" hex escaped chars
to a file using:
sprintf(buf, "0x%x", test_string[i] & 0xFFFF);
write buf to file...
where test_string is a wchar_t
I now need to read this back into another app for rendering.
I am pretty sure I need to use sscanf, but I am not sure how to get it back into wchar_t format.
Any help would be greatly appreciated.
If you are writing them one per line, then you can read each line into a buffer, then use:
sscanf(buf, "0x%x", &test_string[i]);
Or you can read it directly from the file with:
fscanf(fp, "0x%x\n", &test_string[i]);
If you aren't writing each on a separate line, then it's not as easy. But you can make it easy by making each part written 6 bytes:
sprintf(buf, "0x%04x ", test_string[i] & 0xFFFF);
That way you can read in six bytes, and use sscanf():
sscanf(buf, "0x%x", &test_string[i]);
Thanks for the info.
I'm wondering now if there would be a better way to store my strings.
My input files will contain other information than text.
An example record would be:
<font,font size,r,g,b, xpos, ypos, string>
Would it be possible to store a utf-string in the string portion?
If so, would it be relatively painless to do any necessary conversions and load it into a wchar_t?
I am aware of the iconv function, but I have yet to find any useful examples of how it would apply in my case.
>Would it be possible to store a utf-string in the string portion?
You kind of lost me. Can you explain it a little better? And also, what is a utf-string?
It is my limited understanding that unicode can be expressed in utf springs by combinations of characters.
For example, ";uÏP" represents two CJK(chinese, japanese, korean) characters. ";u" being the first and "ÏP" being the second.
I was just wondering if something like that might be a simpler approach.
It sounds like it would be simpler. You could just read in:
<font,font size,r,g,b, xpos, ypos, string>
as a string with fgets(), then parse each part.
