Currently, custom bibliographic styles are not applied to the document when imported. Introducing an event will allow the user to provide the custom bibliographic style implementation and apply it to the document.

Implement hyphenation in RadRichTextBox for different languages. 

Currently, when a page break is added to the document, the paragraph is not split in two. 
It will be better to split the paragraph and add one additional paragraph in order to achieve a more consistent look of the document when applying a style, adding one of the paragraphs to a list or having different first line/hanging indentation of the paragraphs.

The hyperlinks are not exported properly to DOCX, RTF and HTML format if the HTTP:// prefix is not added in the address when they were created.

Steps to reproduce:
1. Open RadRichTextBox and click on Insert tab -> Hyperlink
2. In address field type: www.telerik.com
3. Export the file to DOCX, RTF or HTML format
4. Open the exported file and click on the hyperlink
Observed result: The hyperlink is pointing to a local resource instead of opening the URL.

As a workaround, the regex used to match a partial hyperlink could be further extended. If this regex succeeds in matching a partial hyperlink the HTTP:// prefix will be automatically added to the partial hyperlink. Here is example of how the regex should be accessed:
(this.radRichTextBox.InsertHyperlinkDialog as RadInsertHyperlinkDialog).HyperlinkPattern

When document with large images (the original image cannot fit on the page without resizing) are exported to PDF, the PDF document is visualized distorted by Adobe Reader.

The issue is regression, introduced in 2017 R1 SP1.

Workarounds: 
- Use images that can fit on the page.
- Zoom RadRichTextBox to scale which allows the large images to fit fully on the page.

The fix is available in LIB Version 2017.2.627.

When cells with borders are copied from Microsoft Excel and pasted in RadRichTextBox, some of the borders are missing depending on their type - for example double borders, but also some other types.

Inserting carriage returns in table cell until floating UI container is moved to another page causes a crash.

Some fonts doesn't include bold and italic font styles. Currently text formatted with such fonts and with applied bold or italic formatting is exported without the italic or bold effect. Instead, the default typeface can be exported, and additional transformation could be applied to the letters itself - e.g. skew transform for the italic.

RadDocument.StreamFromUriResolving is not raised for the main document when InsertPictureField is included in header or footer.

RadRichTextBox: Add import/export in the following formats: .mht .odt .epub .doc

Pasting HTML content causes RichTextBox to insert a paragraph break, even if the copied content did not include the end of the paragraph.

Steps to reproduce:
1. Copy the first few words in a paragraph from Internet Explorer
2. Paste into the middle of a sentence in the RichTextBox
Expected: The content is pasted inline
Observed: The content is inserted, but a paragraph break is inserted after the content

In Windows 10 1709 Falls creators update there is an upgrade to Microsoft Edge, with which the copy from edge is changed:

1) no longer it is copied in "Rich Text Format"

2) the "HTML Format" data is formatted differently than before - different line separators and the whole html is placed into a single line (unlike before).

Implement built-in support for the Sogou Pinyin Input Method Editor.

Sogou Pinyin is the most popular IME in China (above 80% of the users are using it).

Currently RadRichTextBox doesn't support Sogou Pinyin IME out of the box, and the users have to manually implement it, as described in the "How to implement your own IME support?" (
https://docs.telerik.com/devtools/wpf/controls/radrichtextbox/ime-support#how-to-implement-your-own-ime-support ) help article and the CustomCaret (https://github.com/telerik/xaml-sdk/tree/master/RichTextBox/CustomCaret ) SDK example. 

The parent of an already removed span cannot be found and a NullReferenceException is thrown while performing Undo. Also, multiple asserts are failing in Debug mode. The stack trace is:

If you highlight a section of text and apply styles to it like bold/italic/underline and place your cursor at the end of that text the Clear All Formatting button does not work. If you turn on those styles and then type some text and place your cursor at the end of that text it does work. The difference in the XAML is that in the first case the styles are only on the span of text itself while in the second the styles are on the span and the paragraph. I have attached a GIF of steps to reproduce and the XAML from the editor before clicking the Clear All Formatting button.

Importing a document with block-level content controls from XAML causes them to become corrupt. If you scroll to a position in which the said control is only partially visible a NullReferenceException is thrown.

A possible workaround would be to initially save the document as a DOCX (just exporting it to DOCX will not fix the issue as the information is already corrupt).

Another way to reproduce this issue:

1. Create a new document and insert a Rich Text Content Control.

2. Save the document as a XAML file.

3. Reopen the XAML file.

4. Move the caret inside the Content Control.

5. Try to insert a new line by hitting Enter - no new line is added as the content control is marked as Inline Level after the import in step 3.

Case 2: 

Create a document with TOC where the content control of the TOC contains some other inlines.

 

The scenario is very common, as in MS Word the option Table -> Layout -> Cell Size -> AutoFit ->  "AutoFit Contents" changes the PreferredWidth of the table and its columns to Auto.
Also the tables imported from HTML have these properties set by default.

Scenarios:
- Auto-sized table occupies minimal space.
- All auto-sized columns in a table (table itself could be, or could be not, auto-sized) should always be sized proportionally to their content length. Currently, such columns are sized equally in the case when there is enough space for all of the content, which is unexpected. (also see the attached images for the scenario with fixed-width table + auto-sized columns).

When applying a bullet/numbered list and track changes are enabled, the change of the bullet/number should be in indicated with the track changes color.

Currently the changes is only visualized as a line left of the paragraph.

Tab stops with visible tab leader (dot, hyphen, underscore) are not exported to PDF.

Steps to reproduce:
- Start with empty document
- In Paragraph Properties dialog, choose Tabs
- In Tab dialog, enter Tab stop position = 2, Leader = underscore, and press Set. Press OK
- Add a word, press Tab, add another word
- Export the text to PDF

Expected: the words are separated with underscores in the exported PDF.
Actual: the words are separated with blank space in the exported PDF.
