### Pretty print output in Jupyter notebook

In order to provide meaningful results to my students in a Jupyter notebook, I would like to pretty print some output, including text, LaTeX and things computed by Sage. I have found that I could combine either `show`

(or `pretty_print`

) and `html`

, or `show`

and `LatexExpr`

. For example,
either

```
limit = r"\displaystyle\lim_{x\to0}\frac{\sin x}{x}="
value = lim(sin(x)/x, x=0)
show(html("Solucion: "+"${}={}$".format(limit,value)))
```

or, instead,

```
limit = r"\displaystyle\lim_{x\to0}\frac{\sin x}{x}="
value = lim(sin(x)/x, x=0)
show("Solucion: ", LatexExpr(limit), value)
```

I would ask the following questions:

- Is there any reason to prefer one approach to the other?
- If I replace
`"Solucion"`

by `"Solución"`

(please note the accented `ó`

), which is the correct way to write this Spanish word, in both approaches I get meaningless letters instead of the expected output. If I use `u"Solución"`

, then Sage raises the error `'ascii' codec can't encode character u'\xf3' in position 6: ordinal not in range(128)`

. Is there a way to use non-English characters?

I am using SageMath 8.5 on a MacBook Pro with macOS High Sierra.
