 |

Hi Pavel, All,
I have a quick test application. It displays a phrase written using devanagari script. It's on the UCS-2 0x9 page, and I have the string encoded as SLV per the other forum posts about using Arabic script. It displays just fine via display_text(), but when I use it as a menu item caption in spider(), it's truncated.
It's almost as if spider() is detecting the number of columns on the screen, and then limiting the displayed text to that many *bytes*. These are multibyte characters, so byte counting wouldn't yield a character length.
The following test case tries to display the same string twice -- first via a spider node, and then via display_text. Again, the display_text() version looks fine, but the menu version created by the spider library is truncated.
I'm using UCS-2 elsewhere in /direct/ calls to select_item(), and getting the correct, full, non-truncated strings. It's just spider that's giving me trouble w/ SLV-encoded UCS-2.
Can anyone please tell me what I'm doing wrong? Thanks so much.
