On a form (CP 1251) user on some fields has to type on serbian (Latin) language and on some others on serbian (cyrilic). Advanced settings for non-unicode programs on "regional and language options" is set to serbian (cyrilic). Font is Times New Roman. How to implement such a behavior without forcing user on a selected form field to switch between keyboard languages (serbian latin or serbian cyrilic)? Is it possible to join somehow language on a specific fields?

For example on field 1 user should see QWE and on field 2 ЉЊЕ (this is a difference between serbian latin and serbian cyrilic) by typing same letters.

Thanks in advance.
