Hi Carlos,

You should read xml tutorial available here:
http://xmlsoft.org/tutorial/xmltutorial.pdf

Starting at 8th page there is a chapter called Encoding Conversion.

If tutorial wouldn't help msg me/us.

Futhermore there are plenty of resources about unicode (utf8/16/32). In very short, you can treat utf8 as way of coding chars in 1 byte-multiple convention. Chars most freqeuntly used are stored in less amount of bytes than less frequently used. There coding codes could be done by Huffman coding, where there is no character, which coding is the same as prefix of less frequently used character. In utf8 you are strongly using CODE PAGEs.

Helpful resources:

Best regards,

HI!

im very new to xmllib, utf8 in C.
im writing a program that will read and write a xml formated config file for other app.
im my application, i use char * all over the place, except on the functions that read from a xmlreader, since the return value of this functions is xmlChar

now, if the library has this special type, its because is needed. is just that i dont get it.

some people at ##C in freenode told me to read about iconv, but it got me more confused ....

so i ask here. should i use xmlChar all arround my app?
should i use a "convert" function? then how is it called?

if you really want to look at it, im hosting my little project it in github

http://github.com/broli/mkixl

warning, the code is ugly as hell, im not only new to xml, but pretty much to C
any help on the matter will be greatly apreciated
