Hi, and welcome to the forum.

I have P_int so that the int can become subscript but once I have i , it transform into special character.

In my version of Open Office, int is an operator which tells the Math component that an integral is to be created. There are several ways to prevent Math from interpreting int as the integral operator. I prefer the %int syntax, which tells Math to use the %int symbol from the catalog. Since there is none, Math uses int as the symbol's value.

Edit: 2019-08-07: The technique in the last line, %int, displayed int in OpenOffice 3.2 but displays %int in OpenOffice 4.1.5. Currently the best solution seems to be P_{ital "int"} for int or other names which match Math operators.
