Lo que da la siguiente imagen:
Como puede ver, el tamaño de los nodos se modifica. ¿Cómo puedo arreglar esto? Gracias por tu tiempo.
Respuesta1
Elimínelo drawde la definición del estilo de nodo o incluya un estándar line width. Debido a que utiliza el solid nodeestilo en trazados con diferentes anchos de línea, los bordes dibujados de estos nodos tienen diferentes anchos de línea y algunos de ellos parecen más grandes que otros.
El siguiente es el resultado de minimizar su ejemplo y agregar line width=0.4pta la definición.
Sería prudente utilizar un paquete como tikz-qtreeo, mejor aún, forest, pero cargarlo sin usarlo no sirve de nada. De manera similar, el problema no depende del uso de escritura no latina y el código no requiere que la mayoría de las bibliotecas estén cargadas en su preámbulo.

forest(o incluso tikz-qtree) le permitiría utilizar una sintaxis menos desordenada y una personalización más potente, incluida una mayor automatización. Incluso simplemente definiendo y aplicando stylescon Ti simplekZ haría que su código sea más claro y flexible.
