Doesn't handle non-standard multi-line values output by Google

[NickSto]

This is technically an issue Google Contacts, not vobject, but it's a compatibility issue that I thought the maintainers might be interested in knowing.

I exported my Google Contacts from the Android app into a .vcf file. This file contains several fields where the value extends to multiple lines, but they aren't indented properly. This causes vobject's parser to choke.

It does include many properly-indented values (usually base64-encoded PHOTO;ENCODING=BASE64;JPEG) where the additional lines are indented with a space character.

But there are many values where it's not indented. The ones I've seen are all QUOTED-PRINTABLE-encoded strings.

Is this a known issue? I didn't see anything on an initial search.

Also, just a quick note about another error parsing Google's file:
It choked on a line like this (only thing changed is the number for anonymity):
TEL;:+1-202-867-5309
Not sure yet if this is similarly out-of-spec.

TEL;:+1-202-867-5309
This problem can be solved!
But if you add a few phone numbers and TYPEs, the problem will turn out!

v = vobject.vCard()
...
v.add('tel').value = "+1-202-867-5309"
v.tel.type_param = ["CELL", "WORK"]

TEL: +1-202-867-5309
  params for  TEL:
    TYPE ['CELL', 'WORK']

If one phone, then everything is OK!
If you add a second, the first phone is overwritten!

...
v.add('tel').value = "+1-202-000-0000"
v.tel.type_param = ["CELL", "HOME"]

  TEL: +1-202-000-0000
  params for  TEL:
    TYPE ['CELL', 'WORK']
  TEL: 
  params for  TEL:
    TYPE ['CELL', 'HOME']

@YuraKursk Hi, thanks for your reply!
I don't think I understand exactly what you're explaining. I'm worried about parsing a vcf with a line like
TEL;:+1-202-867-5309
using vobject.readComponents(). Is that what you're talking about?

Write the code itself. The module vobject is raw.
I wrote the code myself, checks the properties of the phone number! If they are not present, then removes SEMI-COLON (ASCII decimal 59).

@NickSto, here's the option:

s = 'TEL;:+1-202-867-5309'
i = s.find(':')
if i > 0:
    tag = s[:i]
    data = s[i+1:]
    j = tag.find(';')
    if j > 0:
        typ = tag[j+1:]
        tag = tag[:j]
if len(typ):
    typ = ';' + typ
s = tag + typ + ':' + data
print(s)

TEL:+1-202-867-5309

@YuraKursk I see, you're suggesting a way to edit the string before giving it to vobject.readComponents()? I've already done that for the multi-line issue I mentioned at the top. Thanks for the algorithm for avoiding the second issue.
