How to preserve space character in SVG

asked Dec 6, 2018 in Question / help by anonymous

I am creating a component diagram.  In which, I would like the spaces given in between words to be preserved.

e.g.

@startuml
["Hello                World"]
@enduml

The generated PNG preserves the spaces accordingly.

But the generated SVG is not preserving the spaces.  Its like this

How can I preserve the spaces in SVG as well?

I also figured out that the <text> tag of svg has an attribute called "xml:space" which can be set to "preserve" in order to preserve the spacing.

<svg>
<text xml:space="preserve">Hello           world</text>
</svg>

or even the top level stylesheet like the below can also preserve the spacing:

<svg>
<style>
text {
  white-space: pre;
}
</style>
<text>Hello           world</text>
</svg>


So now the question is, how can we specify these attributes or the CSS property in PUML file so that the generated SVG can contain these modifiers for the desired results.

Hello all,

A first workaround will be to use horizontal tabulation '\t':

@startuml
["Hello\t\tWorld"]
@enduml

Here is the PNG result:

Here is the SVG result:

If that can help,

In Plantuml  you can also use Unicode characters...
The "non-breaking space" (<U+00A0>) works to preserve width...

for instance:   

      !$blankSpace = "<U+00A0><U+00A0><U+00A0>"

will not collapse to a single space...
