Hello Tom,
Please use the test source code I previously attached.
** Within the elm_entry object (three chinese characters in the front,
followed by some english letters), click with your mouse on any of the
chinese characters at the start of the string and check stdout. There
are garbage characters returned.
I guess the problem is somehow with the usage of Eina_Unicode. Are
Eina_Unicode strings the same as the usual UTF-8 strings? Please find
below the backtrace of gdb (r50595 evas) for your investigation. The
new evas_common_font_query_char_at_coords() returns the INDEX of the
CHARACTER, while the old evas_common_font_query_text_at_pos() returns
the INDEX of the BYTE of the start of the character. This returned
value is kept as _Evas_Textblock_Cursor's pos. Does 'pos' mean the
number of bytes into the string or the number of character into the
string? I guess the recent discussion of the docs would help here.
:-)
