ConditionalPanel problems when condition has special characters

After several days and trial and error I finally pin down a problem with my conditionalPanel's

conditionalPanel(condition = "input.ingreso_departamento== 'Quiché'",selectInput("ingreso_municipio_qc","Municipio",choices=c(
"Canillá"))

Found out that the special characters are affecting the behavior of my app when deployed.
Regardless if I set options with UTF or environmental to "sp" (spanish)
My bet is that the condition that contains the special characters are the one making problem, which are the ones that I cannot convert to utf8.

So, how do I deal with special characters inside the condition of a conditionalPanel?
Thank you
