在一定程度上，汉字在法国殖民统治时期仍继续被教授。总督府于1917年颁布的《学政总规》（Règlement général de l'Instruction publique）规定，小学阶段每周教授汉字1.5小时，同时在高年级（相当于小学四、五年级）每周教授至少12小时的法语。在中学阶段，每周教授3小时的国语课程（包括汉字和国语字），而法语与法国历史的课程则为每周12小时。[34]
2022年，民间组织越南漢喃復生委員會（越南語：Ủy ban Phục sinh Hán Nôm Việt Nam，委班復生漢喃越南）公布了第一个喃字标准化方案《常用标准汉喃字表》[42][43][44]。该表内共含5524个标准汉喃字（越南汉字及喃字），约覆盖现代越南语日常读写的98%，并建议其中3993个应在中小学教育阶段学习。根据该表的说明，其选字主要基于历史上惯用的形態，但是为了适应现代的精准化表达以及减少一字多音的现象，也有一些字并非與历史常用写法完全一致，但都尽量采用与历史用字相同的声旁或在歷史用字的基礎上增加形旁[42]。在公布一年后，根据一年以来的各种意见，该组织于2023年6月又对部分选字进行了微调并補充了大量連綿詞的推薦寫法，发布了正式版的《常用标准汉喃字表》，并将字表所用字体由此前的新细明体改为了基于开源字体思源宋体的源明体（越南語：Minh Nguyên，明源）。該字體說明中指出其採用的具體字形遵从近現代明朝體的一般寫法而非按照喃那宋的形態製作，基本相當於中文語境下的舊字形[45]。

Many of these entries ... Vietnam were written in either Nôm or Hán-Nôm rather than in 'pure' Chinese. My initial impression was that the percentage of texts written in Nôm was even higher. This is because for the particular medical subject I wished to investigate-smallpox-the percentage of texts written in Nom or Hán-Nôm is even higher than is the percentage of texts in Nôm and Hán-Nôm for general medical and pharmaceutical .."

^Marr 1984，第141頁: "Because the Chinese characters were pronounced according to Vietnamese preferences, and because certain stylistic modifications occurred over time, later scholars came to refer to a hybrid "Sino-Vietnamese" （Han-Viet） language. However, there would seem to be no more justification for this term than for a fifteenth-century "Latin-English" versus the Latin written contemporaneously in Rome."

"Even at this moment, the so-called "Confucian scholars （i.e. those who have studied Chinese characters, and in particular, those who have passed the degrees of cử nhân [bachelor] and tiến sĩ [doctorate]） do not know anything, I am sure, of Confucianism. Yet every time they open their mouths they use Confucianism to attack modern civilization – a civilization they do not comprehend even a tiny bit."
