Garbled characters in auto-posted content — curly quotes turning into “’”, emoji showing as boxes, accented letters replaced with question marks — almost always trace back to one specific cause: a mismatch between the character encoding your feed declares and the encoding it actually uses. It’s one of the more common, and more confusing, technical issues in RSS auto-posting, because the feed itself often looks completely normal when opened directly.
RSS feeds are XML, and XML files declare a character encoding at the top (almost always UTF-8 today) that tells any tool reading the feed how to interpret the bytes that follow. If your CMS, a plugin, or a manual edit introduces content in a different encoding than the feed declares — or the feed’s declared encoding doesn’t match what’s actually being output — special characters get misread. A smart quote saved in one encoding but read as another turns into exactly the kind of garbled two-or-three-character mess (“’” for a simple apostrophe) that’s the most common symptom of this problem.
The most frequent source is copy-pasting content from Microsoft Word or another tool that uses different default encodings and “smart” typographic characters (curly quotes, em dashes, ellipsis characters) that don’t always survive a copy-paste into a CMS cleanly. A close second is a CMS or plugin misconfiguration that outputs the feed in a different encoding than the site’s main pages use, which can happen after a migration, a plugin update, or a custom feed template that doesn’t inherit the site’s normal encoding settings correctly.
Open your raw feed URL directly in a browser and look at the specific characters causing trouble — if they’re garbled in the raw feed itself, the problem is in feed generation, not in whatever tool is auto-posting from it. Check the encoding declaration at the very top of the feed’s XML (<?xml version="1.0" encoding="UTF-8"?> is the standard, correct declaration) and confirm it matches what the feed actually contains. If the raw feed looks correct but posts still come out garbled, the issue is more likely in how the auto-posting tool itself is parsing or re-encoding the content, which is worth reporting directly rather than trying to fix on the feed side.
For content pasted from Word or similar tools, using your CMS’s “paste as plain text” option, or a plugin that strips smart-typography characters into standard equivalents, prevents the mismatch at the source rather than trying to fix it after publishing. For feed-level encoding mismatches, confirming your CMS’s feed template explicitly declares and outputs UTF-8 consistently — the safest, most universally-supported choice — resolves most cases; this is typically a one-time settings or template fix rather than something that needs repeating per post.
Not every broken character is an encoding mismatch. A second, very common symptom is text like &, ’ or " appearing literally in a social post where an ampersand, an apostrophe or a quotation mark should be. This happens when a feed template escapes content that was already escaped, so the HTML entity itself gets encoded a second time. A reader or auto-posting tool decodes the feed once, as it should, and is left with the entity code instead of the character.
You can spot this in the raw feed: an ampersand inside a title should appear as & exactly once, not as &amp;. If you see the doubled form, the fix is in the feed template or in a plugin that modifies titles and excerpts, not in the posting tool.
The quickest way to catch encoding problems is to test them on purpose, before the first real post goes out to your audience:
This small check is especially worthwhile for sites in languages with many accented or non-Latin characters, and for feeds that go to many networks at once. PostRSS can post one feed to many targets, from Facebook Pages to Telegram channels and team chats, so a character problem that slips through would otherwise appear everywhere at the same time.
When the feed is clean, the rest is straightforward: PostRSS builds each post from the title, the description, the page title or your own static text, depending on the message format you choose. The features page describes these formats in detail.
Browsers are often forgiving about encoding mismatches and silently correct display even when the underlying declaration is wrong; an auto-posting tool parsing the raw XML more strictly can surface a mismatch a browser papers over invisibly.
Mostly special characters — smart quotes, em dashes, accented letters, and emoji specifically — since plain ASCII text (standard English letters, numbers, basic punctuation) is represented identically across virtually every common encoding and rarely shows visible corruption.
Yes, for virtually every modern website — it’s the universal standard that correctly represents every language’s characters and emoji, and every major CMS defaults to it. Consistently declaring and actually using UTF-8 throughout your site and feed avoids this entire category of problem.
Garbled special characters in auto-posted content are almost always an encoding mismatch between what your feed declares and what it actually contains, most often introduced by pasted content from another tool or a misconfigured feed template. Checking the raw feed directly, confirming a consistent UTF-8 declaration, and avoiding raw pastes from Word-like editors resolves the overwhelming majority of cases.
