EncConv: simplified code of LConvEncoding
« on: September 16, 2019, 12:39:22 pm »
EncConv is simplified code of LConvEncoding from Lazarus.
it uses the same codepage tables.

changes:
- type of encoding ID is now enum
- removed using of FPC string convertion API, removed using of Unix iconv;
  so unit must work the same way on all platforms and FPC versions
- removed optional changing of CodePage for resulting string
- renamed most of functions, except simple functions like UTF8ToNNN, NNNToUTF8
- added EncConvErrorMode global var, which has 4 possible values
  (LConvEncoding global var had 2 values):
  raise exception, skip chars, replace chars with '?', return empty string
- removed parameter Encoded of functions

Looks like Pre FPC 3.0 code. It stuffs encodings into bytes without setting the encoding.

These are not conventions that are used anymore.

The code even fails in trunk.
Alex what version are you using?
Black themes should be banned.

@marcov
Code was needed for ATSynEdit, which holds list of string (TFPGList<StringItem> which has string). so FPC 3 codepages were not needed for me.

@Thaddy
I tested it on Linux in FPC 3.2 and 3.3 2019/04/26.

Updated FPC 3.3 from svn today. Again all works.
Demo must show "ok" for tests 1,2 and show "failed" for test3 (it must fail by design).

Updated the component:

+ add: support encoding iso-8859-7
+ add: support encoding iso-8859-10
+ add: support encoding iso-8859-13
+ add: support encoding iso-8859-5
+ add: support encoding iso-8859-14
+ add: support encoding iso-8859-16

I also send the patches of these encodings to LConvEncoding, but for those ppl who don't use Lazarus trunk, it's not possible to use these last changes.
Last 3 encodings ( -10, -7 and -13 ) are not merged to Laz.
So use EncConv.

+ add: support encoding iso-8859-3.

Anybody needs more ISO-8859 encodings?
Any other encodings (1-byte codepages)?
