基本操作之——Unicode编码

自版本18.11后，支持UTF-8

1.字符转Unicode码

tuple_ord ('s', Ord)
dev_clear_window()
dev_disp_text('\'s\'的Unicode码为'+Ord, 'window', 'center', 'center', 'black','box_color', '#00ffffc0')

dev_clear_window()
dev_disp_text('\'一\'的Unicode码为'+Ord, 'window', 'center', 'center', 'black','box_color', '#00ffffc0')

tuple_ord ('凡', Ord)
dev_clear_window()
dev_disp_text('\'凡\'的Unicode码为'+Ord, 'window', 'center', 'center', 'black','box_color', '#00ffffc0')

tuple_ords ('s一凡', Ords)
dev_clear_window()
dev_disp_text(Ords+'转为十六进制为'+Ords$'#X', 'window', 'center', 'center', 'black','box_color', '#00ffffc0')

 2.Unicode码转字符

tuple_chr (0x73, Chr)
dev_clear_window()
dev_disp_text('Unicode码0x73对应字符为'+Chr, 'window', 'center', 'center', 'black','box_color', '#00ffffc0')

tuple_chrt ([0x73,0x4E00,0x51E1], Chrts)
dev_clear_window()
dev_disp_text('Unicode码[0x73,0x4E00,0x51E1]对应字符为:'+Chrts, 'window', 'center', 'center', 'black','box_color', '#00ffffc0')

* 
* From 18.11, HALCON supports UTF-8.
