Text Formatting ⇒ How can I forbid something to be put at the end of a line?

[hyc_n]

I wrote several lines like

Code: Select all

\newcommand{\aaa}{{\bfseries\tiny a}}
\newcommand{\bbb}{{\bfseries\large b}}

which just print a number/letter formatted in some fixed way.
These number/letter will appear throughout the text very often.

But, sometimes the number/letter appear at the end of a line, the way which I do not prefer.

How can I rewrite so that the number/letter starts a new line if it comes very close to the end of a line?

Please clarify the purpose of these commands and their application by a proper minimal example.

I am sorry for my not giving a minimal example.

Code: Select all

\documentclass{article}
\newcommand{\rrr}{{\sffamily\tiny\raisebox{0.2pc}{\=r}}}
\usepackage{CJKutf8}
\begin{document}
\begin{CJK*}{UTF8}{song}
一二三四五六七八九十一二三四五六七八九十一二三四五六七八九十一二\rrr三四五六七八九十\par
one two three four five six seven eight nine ten one two three four five six \rrr seven eight nine ten
\end{CJK*}
\end{document}

I want to have my "\rrr" start a new line in the Chinese example, as it does in the English example.

In English a space appears between words. This space also teaches LaTeX to start a new line if necessary. However,
no space is placed between CJK characters to separate words, so nothing can tell LaTeX to start a new line.

I failed to tell LaTeX to start a new line with "\rrr" unless I add a space somewhere appropriate, but this will results in undesired spaces. Can anyone help me tell LaTeX to start a new line with "\rrr" whenever it comes near the end of a line without adding a space, please?
