Problem with "datenum" and "datetime" functions

I need to extract date information from a formated date string. I have used both datenum and datetime functions but both of them returned an error. However, when I run the code on a different computer it worked well. Here is the simple code and the corresponding error:
Example for DATENUM:
datenum('11/02/2005 13:10:00','dd/mm/yyyy HH:MM:SS')
datenum('11/02/2005 13:10:00','dd/mm/yyyy HH:MM:SS')
↑
Error: Invalid text character. Check for unsupported symbol,
invisible character, or pasting of non-ASCII characters.
Example for DATETIME:
datetime('11/02/2005 13:10:00','InputFormat','dd/MM/yyyy HH:mm:ss')
datetime('11.02.2005 13:10:00','InputFormat','dd.MM.yyyy HH:mm:ss')

Error: Invalid text character. Check for unsupported symbol,
invisible character, or pasting of non-ASCII characters.
Why don't the functions work on my computer?

I was able to reproduce this by copying your code from above. It appears the opening ( is bad (right where the arrow is)
datetime('11/02/2005 13:10:00','InputFormat','dd/MM/yyyy HH:mm:ss')
Deleting your ( and replacing with my ( fixed it.
Further investigating it looks like there is an invisible character after the (
int32('(')
ans =
1×2 int32 row vector
