Help Meeee!! Lemur Editor does not make me special character

[pulsar]

Hi people ... I have a MacBookPro with OS Yosemite and trying to insert a script in a specific button does not make me enter special characters as if I write them in Text Edit functions normally.
If I try to copy the script from Text Edit to lemur with Cmd + V Lemur closes and then it appears an error window.
Who will help me solve this problem?
Thank you

Can you post the code you're trying to paste? Then other can try if it gives them the same problem
