* Fixed regoff_t documentation for wide characters.
|
||
|
|
The documentation erroneously claimed that offsets are always given in
|
||
|
|
bytes (they are bytes in byte and multibyte strings, but wchar_t
|
||
|
|
offsets in wchar_t strings).
|
||
|
|
|
||
|
|
Thanks to Gregory Sharp for pointing this out.
