uneven splitting of codepoints

[markroxor]

As per the above screenshots the codepoints on the edges of the terminal session are messed up because the number of columns "breaks-through" the code points.

Copying from our earlier email conversation:

I think we need to check if the codepoint at COL is valid or not. If not, try the prev one and so on...
The function mblen() might be of help (no need to do a wchar conversion).

I figured out the actual length of the file name (including the MB length). How can we decide that while resizing the terminal the string should break at a particular code point? any ideas/?

I think you need to keep checking for valid codepoints (using mblen) till it exceeds the total length of the columns.
