Introduction

When working with LaTeX, it's not uncommon to encounter unexpected linebreaks and glue behavior, especially when using different fonts. In this article, we'll delve into the strange linebreak and \noindent glue behavior with different fonts, exploring the underlying causes and potential solutions.

The Problem

Let's start with a simple example. Consider the following code compiled with XeLaTeX:

\documentclass{article}
\usepackage[margin=1in]{geometry}
\begin{document}
{\large \textbf{A Gradient of Colors}}
\noindent This is a paragraph with a gradient of colors.
\end{document}

When compiled, the output may look something like this:

A Gradient of Colors

This is a paragraph with a

Notice the unexpected linebreak after the title. This behavior is not limited to this specific example; it can occur with different fonts and font sizes.

The Role of Font Metrics

Font metrics play a crucial role in determining linebreaks and glue behavior. Font metrics include information such as font size, font family, and character spacing. When using different fonts, the font metrics can change, leading to unexpected linebreaks.

The Impact of \noindent

The \noindent command is used to prevent indentation at the beginning of a paragraph. However, when used with different fonts, it can lead to unexpected glue behavior. The \noindent command can interact with font metrics in complex ways, resulting in unexpected linebreaks.

The Role of XeLaTeX

XeLaTeX is a typesetting engine that uses the XeTeX engine to process LaTeX documents. XeLaTeX is known for its ability to handle complex font metrics and Unicode characters. However, it can also lead to unexpected linebreaks and glue behavior when used with different fonts.

The Solution

To avoid unexpected linebreaks and glue behavior when using different fonts, follow these best practices:

Use font packages: Use font packages such as fontspec or unicode-math to manage font metrics and ensure consistent behavior.
Specify font sizes: Specify font sizes using commands such as \large or \Huge to avoid unexpected font size changes.
Use \noindent carefully: Use \noindent carefully, especially when working with different fonts. Consider using alternative commands such as \indent or \parindent to control indentation.
Check font metrics: Check font metrics using tools such as fontspec or unicode-math to ensure consistent behavior.
Test thoroughly: Test your document thoroughly to ensure that linebreaks and glue behavior are consistent across different fonts and font sizes.

Conclusion

In conclusion, strange linebreak and \noindent glue behavior with different fonts can be a challenging issue to resolve. By understanding the role of font metrics, the impact of \noindent, and the behavior of XeLaTeX, you can take steps to avoid these issues. By following best practices and testing thoroughly, you can ensure that your documents look professional and consistent across different fonts and font sizes.

Additional Tips and Tricks

Use font families: Use font families such as serif, sans-serif, or monospace to ensure consistent behavior across different fonts.
Specify font encodings: Specify font encodings using commands such as \fontencoding{T1} or \fontencoding{EU1} to ensure consistent behavior.
Use font features: Use font features such as fontspec or unicode-math to manage font metrics and ensure consistent behavior.
Check font compatibility: Check font compatibility using tools such as fontspec or unicode-math to ensure that fonts work well together.

Common Issues and Solutions

Unexpected linebreaks: Use \raggedbottom or \flushbottom to prevent unexpected linebreaks.
Glue behavior: Use \noindent carefully or consider using alternative commands such as \indent or \parindent.
Font metrics: Use font packages such as fontspec or unicode-math to manage font metrics and ensure consistent behavior.

Best Practices for Working with Fonts

Use font packages: Use font packages such as fontspec or unicode-math to manage font metrics and ensure consistent behavior.
Specify font sizes: Specify font sizes using commands such as \large or \Huge to avoid unexpected font size changes.
Use \noindent carefully: Use \noindent carefully, especially when working with different fonts. Consider using alternative commands such as \indent or \parindent.
Check font metrics: Check font metrics using tools such as fontspec or unicode-math to ensure consistent behavior.
Test thoroughly: Test your document thoroughly to ensure that linebreaks and glue behavior are consistent across different fonts and font sizes.

Conclusion

Q: What causes strange linebreaks and glue behavior with different fonts?

A: Strange linebreaks and glue behavior with different fonts can be caused by a combination of factors, including font metrics, the impact of \noindent, and the behavior of XeLaTeX. Font metrics, which include information such as font size, font family, and character spacing, can change when using different fonts, leading to unexpected linebreaks. The \noindent command can also interact with font metrics in complex ways, resulting in unexpected glue behavior.
