    <p>I am developing a presentation with the use of <code>R</code> <code>slidify</code> function. In my presentation I use <strong>diacritic marks</strong> from Polish language (Ą,Ć,Ę,Ł,Ń,Ó,Ś,Ź,Ż). I have noticed that their display (only in case of the presentation title slide) does differ depending on whether I render its html view via <code>Knit HTML</code> button in <code>RStudio</code> or I view the html file output generated by the <code>slifidy</code> function. </p> <p>This is a screen from a "Knit HTML button view" presentation title slide:</p> <p><img src="https://i.stack.imgur.com/rrvSH.png" alt="enter image description here"></p> <p>This is a screen from an html file output generated by the <code>slifidy</code> function (in which I additionally marked some of outstandingly displayed marks):</p> <p><img src="https://i.stack.imgur.com/gnYBk.png" alt="enter image description here"></p> <p><strong>Question:</strong> why does such difference in a font type occur and, more important, how to avoid this? (Please note it happens only in the title slide.)</p> <p>My presentation begins with the structure: </p> <pre><code>--- title : Mąlarądóałatrią o (ą,ć,ę,ł,ń,ó,ś,ź,ż ; Ą,Ć,Ę,Ł,Ń,Ó,Ś,Ź,Ż) subtitle : Podtytuł mąlarądóałatrią o (ą,ć,ę,ł,ń,ó,ś,ź,ż ; Ą,Ć,Ę,Ł,Ń,Ó,Ś,Ź,Ż) author : Imię Nazwisko job : Pisanie prezentacji o (ą,ć,ę,ł,ń,ó,ś,ź,ż ; Ą,Ć,Ę,Ł,Ń,Ó,Ś,Ź,Ż) framework : io2012 # {io2012, html5slides, shower, dzslides, ...} highlighter : highlight.js # {highlight.js, prettify, highlight} hitheme : tomorrow # widgets : [] # {mathjax, quiz, bootstrap} mode : selfcontained # {standalone, draft} --- ## Wstęp o ą,ć,ę,ł,ń,ó,ś,ź,ż ; Ą,Ć,Ę,Ł,Ń,Ó,Ś,Ź,Ż [...] </code></pre>

    1. COI suspect it has to do with the encoding of the document. I believe when you do hit Knit HTML, the document is encoded as UTF-8, which leads it to slidify correctly, while the slidify function does not take care of it automatically. I will investigate and figure out the root cause.

    2. COIn RStudio, while saving the Rmd file, can you try Save with Encoding, and ensure that you are saving it as UTF-8?

    3. CO**Ramnath**, thank you for your interest! I do have UTF-8 set as *default encoding for source files*. For being 100% sure I just did the 'save with encoding -> UTF-8', and the result after running `slidify` is the same. Would you consider it a good temporary solution to set a font type to the type we can see in the first screen? (As in the second screen the diacritic marks are displayed *correctly*, it is just the font type which is inconsistent...)

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
