* This file contains utf-8 decoding function that is needed to read
|
|
* utf-8 encoded mails in non-utf-8 locale.

|
|
* Every decoded character consists of n bytes. First byte is octal
|
|
* 300-375, other bytes - always octals 200-277.
|
|
*
|
|
* \a\b characters are decoded to html code octdec(a-300)*64 + octdec(b-200)
|
|
* \a\b\c characters are decoded to html code octdec(a-340)*64*64 + octdec(b-200)*64 + octdec(c-200)

|
|
