It appears that Coda has some difficulties with [some] non-latin characters. Examples are: ž, š, į, ė, ū, ų.
Display is off. Not a big deal but probably related to font:
Another inconvenience - if column heading starts with non-Latin character like above - it is not possible to find it when using reference in formulas. The trick is to use first latin letter first like I, Z, S in the name and then once the formula is built - change the name to non-Latin. I will start a new thread on this. To get the example below I used the name Ziedu valdovas (1) first and after programming a formula - switched Z to Ž.
