Yes, according to C++(C) the types “char”, “unsigned char”, and “signed char” are distinct intrinsict types. The “char” type may or may not be signed [1].
<div class=""><br class="">
</div>
<div class="">However, from a portable I/O perspective, the data must be either “signed” or “unsigned”. I think using fixed with integer types for the byte size is appropriate for portable I/O.</div>
<div class=""><br class="">
</div>
<div class="">Using the “char” type, with its undefined signess for I/O or image processing is a mistake just waiting to happen, which can result in unexpected signed behavior.<br class="">

<div style="font-size:12.8px" class="">I don't have editing privileges for the wiki but I want to respond on the suggestion to use fixed width types. In general, I think this is a good idea. However, for char you have to realize that char, signed char and unsigned
char are three different types. Changing char -> int8_t will therefore always be a real type change (and not only potentially for some platforms). I am not sure if this is desirable as char is quite widely used for 8 bit image representations in other systems/libraries.</div>

<div class="">Hello everyone,<br class="">

I just started a wishlist page for ITKv5. As far as I know, there is no current ITKv5 officially planned but it may be a good location to keep track of the current limitations of ITK and what could be improved in the next major revision that may break some
of the API. Please feel free to add any of your wishes on that page here: <a href="https://itk.org/Wiki/ITK_Release_5/Wish_List" target="_blank" class="">
