When I was young, my mom used to scold me for having bad handwriting. She used to say that handwriting represent one's personality, so I have to have a good handwriting to give a good impression to people. Graphology, also known as handwriting analysis, widely used technique to interpret people's handwriting, supports my mom's claim. Graphologists interpret people's handwriting to identify their personalities. For example, if one writes a letter "h" with long head, one is prone to be proud and ambitious. Also, according to graphologists, splashing comma represent a possible temper. The video linked below shows the example of the interpretation of Michael Jackson's handwriting.

Although many other researches opposed this study for having low reliability and low validity, I still believe that handwriting implies some aspect of people' personalities. For my personal example, I have two brothers whose handwriting is a lot different from each other's. As you can imagine, their personalities are a lot different too. The first brother usually writes in fast pace like sweeping while my second brother write in slow but organized style. Relatively, my first brother is more impatient and less organized than my second brother.
Then, I became wondered how different language affects the interpretation. Because different countries use different symbols, should graphologists learn each language to fully interpret their personality? The interpretation may vary along with language. However, according to the link below, professional graphologists seems to understand different handwriting styles across different language. It implies that graphologists rely on physical fact of handwriting rather than a meaning of symbol to interpret people's personalities.
