I can not insert simple text into mysql with column text [duplicate]

I'm not able to do a simple update to a table that contains a TEXT column. I put a simple Spanish text however the sql returns me error saying that line is too large. But it is a very small phrase. Here is the error code:

SQL query error: Edit

UPDATE ppplaw.sobre SET pol_gestao_esp = 'Para la continuidad de
la excelencia en la prestación de servicios jurídicos y de la
satisfacción de nuestros clientes, colocamos todos los esfuerzos'
WHERE sobre.id = 1
