Question: Problem with 'alias'

Refers to yMaple 2019.1

The command alias(X(s)=laplace(x(t),s,t)) will not be executed in the  code following it. It seems that the 'funny font' L used instead of the word 'laplace' ist not recognized. Maple 2018.2.1 works fine, since it doesn't use the 'L" but works with 'laplace'. Is there a fix ?
