Since an e with an acute accent is a pain to type, I have a macro for the name Bézier:
\def\Bez{B\'{e}zier}
I swear this used to work fine, but today I tried typing
The so-called \Bez curve is not really based on \Bez's original ideas.
And the output I got was
What happened to the space before the word "curve"?
If I add a space to my macro definition, then "Bezier curve" comes out right, but "Bezier's work" get's an extra space. What should I do?

\Bez\or\Bez{}to get a space. – marv Jul 16 '22 at 06:01Bézieris fine. – frougon Jul 16 '22 at 06:04ékey. Other possibilities would be input methods in Emacs and the Compose key in X11. – frougon Jul 16 '22 at 06:10Bézierinto your tex document. – Mico Jul 16 '22 at 06:11ALT + <SPEC.KEY>followed by a letter e.g.eafter releasingALT, whereSPEC.KEYis;,',#,[,],,,.,/(those are on the right-hand side of regular letters on my keyboard).
