Leading space in short label not shown

[andimik]

See attached xml file from Slovene DAB ensemble R1.

Some services have a leading space in the short label, but this is not shown.

Other tools (here: dablin_gtk) show that, on the other hand.

Yes, I am trimming both service name and short name. Honestly I do not like that they are trying to get prominent position in service list by starting service/short name with space. Since most of the information is displayed using html technology keeping space at the beginning of short name will probably have no visible impact. Is it important to show that show name starts with space?

[andimik]

In Ensemble Information window it makes sense not to trim it, as you already quote it. Plan is to export this to FMLIST or similar.

This is what is actually transmitted for VAL 202 service:

	0x9202	'VAL 202         ' [ '1E00' ]   PTY: 09  (static) | charset 0x00 | NumComponents 1 
		AudioComponent (primary), SCIdS: 0, Label: 'VAL 202         ' ['1E00'], ASCTy: 0x3F, 
			SubChId: 1, Language: 38, StartCU: 96, NumCU: 102, EEP 3-A, Datarate: 136kbps, NumUserApps: 1
				UserApp 1/1: UAType: 0x2 [0C3C], X-PAD data: Type=12, DG=0, DSCTy=0x3C, Label: ''

1E00 is bitfield that means ' 202'

So why to keep leading space and remove trailing space? I am not sure about this issue.

EDIT: by the way, standard clearly states [5.2.2.2]: "Bytes at the end of the character field that are not required to carry the label shall be filled with 0x00."

They have changed the labels, btw.

The leading space is now only for 4 services.

The question is valid. I have tried to remove trimming but it will not help in ensemble view. I would have remove formatting and display it in fixed font to visualise all spaces as they are (eg. trailing spaces in service label)

[KejPi]

This is how it looks like when service labels are not trimmed and <pre> tag is used, I do not like it :-(

[andimik]

<pre>

If this is HTML, why not replace each space with  ?

[KejPi]

This is exactly what I do not want to do.

[andimik]

BTW

If the leading space is in the long label, then you see it in AbracaDABra.

Well, that surprises me too :-D
But looking at the related commit, it seem that I have changed the implementation in the way that I am removint trailing spaces not leading. But it does not look good in the service list to be honest :-(
